When you start a debugging session the IDE opens some debugging windows by default. In addition to the main Debugging window in the left pane of the IDE, other debugger windows open as tabs below the editor. You can open any debugger window by choosing Window Debugging window name for example, Window Debugging Breakpoints. Each debugger window displays a variety of icons to relay information about the object. For example, the Breakpoints window uses a small red square to indicate a breakpoint set on a line. Java Swing Projects IdeasJava student projects A variety of suggested student term projects involving Java. These are not beginner exercises. The goal of this Project was to produce an opensource reference implementation of the Java SE 8 Platform Specification defined by JSR 337 in the Java Community Process. Java concepts. Java was developed to achieve 5 main goals. These are It should be simple, objectoriented, distributed and easy to learn. It should be robust and secure. Master Java Programming Building Ten Projects. Java is the world most popular language and it powers billions of devices and systems worldwide. Some windows also include a node expansion control to the left of the icon. Clicking this control expands and collapses the object. The Debugging window opens in the left pane of the IDE and uses a tree structure to display the threads and calls in the current debugging session. The current thread and call are displayed in bold. You can expand the node for suspended threads to view the call stack. In the debugger tabs, information is organized into lists. Each list item represents a single object. Each column represents a property of the object. Data displayed in blue underlined text is linked to the source code. Some elements of lists in the debugger tabs have editable properties, such as the value property of a variable in the Variables window. If you select a property and the property has a white background you can edit the property. A selected property with a gray background cannot be edited. Customizing a Debugger Window. You can rearrange elements of a debugger window or remove columns to display only the information of interest. To add or remove a column to a window Click to the right of the column titles or right click in the window and choose List Options Change Visible Columns. Click the appropriate checkbox to turn the display of information on or off. Click OK. To rearrange the columns in a window Drag the column header to the right or left to place the column in the new location. To set the sort order of a window Right click anywhere in the window and choose List Options Sort sort order. For all windows, you can sort the column in ascending or descending order. A triangle is displayed in the column header. The direction in which the triangle is pointing indicates whether the sort order is ascending or descending. Some windows provide additional sort orders. Choosing Current Context in the Debugger. The current context is the portion of your program on which the debugger is currently focusing. When multiple sessions are running, only one session is current. Within the current session, the thread from which the debugger regained control is the default current thread. Inside the current thread, the most recent call is the default current call. You can make any session, thread, or call current by right clicking its node in the appropriate debugger window and choosing Make Current. Debugger Windows and Context. Most debugger windows depend on the current context. When you change the current context, the contents of these windows are updated to reflect the new context. For example, the Debugging window shows the threads in the current session, while the Call Stack window shows the call stack for the current thread. The Variables window shows the variables that are local to the current call, and the Loaded Classes window shows the classes that have been loaded by the current session. For more information on viewing classes and class instances, see Section 9. Viewing Program Information When Debugging. The exceptions are the Breakpoints and Watches windows. These windows list all breakpoints and watches set in the IDE. While the set of watches is shared by all sessions, an individual watch expression is evaluated and displayed based on the current context. For information on setting breakpoints, Section 9. Managing Breakpoints. For information on debugging threads, see Section 9. Debugging Threads in the IDE. For information on examining the call stack for the current thread, see Section 9. Using the Call Stack. The Source Editor and Context. When a variable is active in the current context, the Source Editor displays the value of the variable when you move the pointer over it. In cases where a program includes different variables with the same name, the Source Editor displays the value based on the current context, and not on the instance of the variable in the source code. Attaching Source Code to a JAR File. When you add a JAR file or folder of compiled classes to a projects classpath, it is often useful to add the source files for those classes so that you can view their contents when working with them. Attaching source code to a JAR file or compiled classes folder lets the IDE know where to find the source code for those classes. You can then step into the source files when debugging and open the source files with the Go To Source command. Note For code completion to work properly in the IDE, you must either attach a complete set of source files as a folder or add the available source files as a Zip archive. To attach source code to a JAR file or compiled classes folder Choose Tools Libraries from the main menu. In the left pane of the Ant Library Manager, select the project library within which the JAR file you want to add the source code to is located. Only libraries already registered with the IDE are listed in the Ant Library Managers Class Libraries list. If the JAR file or classes folder for which you want to add the source code has not already been added to a registered library, create a new empty library using the New Library button. In the Classpath tab click Add JARFolder and specify the location of the JAR file containing the compiled class files. A class library can contain multiple JAR files as well as their Javadoc documentation and source code. In the Sources tab, click Add JARFolder to add the folder or archive file containing the source code. Click OK to exit the Ant Library Manager. The IDE adds the selected JAR files and source code to the specified library and automatically registers the source code in every project that has that JAR file on its classpath. When you create a Java class library for a single JAR file, you can simply add the JAR file to the projects classpath to make the associated Javadoc and source code available. If your Java library contains multiple JAR files, however, you must add the library itself to the classpath. Adding the library to the classpath also makes it easier to share the project with other developers. For information on setting the classpath, see Section 5. Managing the Classpath. You can also associate the sources with a JAR file using the projects Project Properties window. However, doing so creates the association only for that project. To associate sources with a JAR file through the Project Properties window Open the Project Properties dialog box by right clicking the project node and choosing Properties. Select the Libraries node in the Categories pane. Select the JAR with which you want to associate the sources and click Edit. Specify the sources to be associated. To attach source code for a Java platform Choose Tools Java Platforms from the main menu. Select the platform in the left pane of the dialog box. In the Sources tab, add the folders or archive files containing the source code. Java programming language Simple English Wikipedia, the free encyclopedia. Java is object oriented. Unchanged C or C code will not work in Java, in most cases, though Java looks much like C and C. Java can run on many different operating systems. This makes Java platform independent. Java does this by making the Java compiler turn code into Java bytecode instead of machine code. This means that when the program is executed, the Java Virtual Machine interprets the bytecode and translates it into machine code. R Link Toolbox. Java was developed to achieve 5 main goals. These are 12It should be simple, object oriented, distributed and easy to learn. It should be robust and secure. It should be independent of a given computer architecture or platform. It should be very performant. It should be possible to write an interpreter for the language. The language should also support parallelism and use dynamic typing. The Java platform refers to a group of software products from Sun Microsystems. The platform is used to develop and run Java programs. The platform includes the execution engine called a Java Virtual Machine that allows Java programs to do the same thing on different computer systems. This capability of being able to develop software on one platform and running it on other platforms is called cross platform capability. Instrument Manual.

Swing application used to build an application that has a GUI windows, buttons, menus, etc. EJB runs on a web server and is used to develop large, complex websites. Java is commonly used to teach students how to program as a first language, yet is still also used by professionals. Java requires that each variable be initialized. Some older languages such as C, allow variables to go uninitialized, which can cause random failures with mysterious bugs. Java requires that each method that declares a return type, always return a value. This also prevents bugs. Java comes with a large set of classes and methods, the Java API that can be used without having to develop as much code from scratch. Unlike C, Java primitive types, such as int, are always the same size in the number of bits which helps achieve cross platform compatibility. Java used to be thought of as being slower than C, but thats less important in recent years with computers being faster. Java has exception handling that requires a programmer to handle error conditions such an InputOutput errors. Code compiled on one Java platform can be run on other platforms that support Java without modification of either the source code nor the byte code. For example, this means that a person can make a Java program for a Windows computer and have it run a Linux computer or a Mac computer. The programming language Java has also been criticized. Some of the criticisms are Generics were added to Java in such a way so that existing code would still keep running. This was done using type erasure. This means that during compilation, the actual type of a generic argument is removed. This can lead to the Java interpreter to behave in unexpected ways at times. Java has no unsigned integer types, which languages like C heavily use. This also means that it is impossible to directly exchange numeric data between C and Java programs. Cryptography also relies on such types to some extent this makes it more difficult to write applications that use cryptography in Java. The IEEE has defined a standard for floating point arithmetic, IEE 7. Java only supports a part of the features of this standard.
