How to Download and Install Eclipse to Run Java
But you can RUN your program with warnings. This will save you many agonizing hours trying to figure out how to do somethings later. Able to use a graphics debugger to debug program is crucial in programming. It could save you countless hours guessing on what went wrong. A breakpoint suspends program execution for you to examine the internal states e. Before starting the debugger, you need to set at least one breakpoint to suspend the execution inside the program. Set a breakpoint at main method by double-clicking on the left-margin of the line containing main.
A blue circle appears in the left-margin indicating a breakpoint is set at that line. The program begins execution but suspends its operation at the breakpoint, i. As illustrated in the following diagram, the highlighted line also pointed to by a blue arrow indicates the statement to be executed in the next step.
At each of the step, examine the value of the variables in the „Variable“ panel and the outputs produced by your program in the „Console“ Panel , if any. You can also place your cursor at any variable to inspect the content of the variable. Single-stepping thru the program and watching the values of internal variables and the outputs produced is the ultimate mean in debugging programs – because it is exactly how the computer runs your program!
As mentioned, a breakpoint suspends program execution and let you examine the internal states of the program. To set a breakpoint on a particular statement, double-click the left-margin of that line or select „Toggle Breakpoint“ from „Run“ menu. You could set a breakpoint at the statement immediately outside the loop e. Alternatively, you can place the cursor on a particular statement, and issue „Run-To-Line“ from the „Run“ menu to continue execution up to the line.
Always terminate your current debugging session using „Terminate“ or „Resume“ till the end of the program. Important: I can’s stress more that mastering the use of debugger is crucial in programming.
Explore the features provided by the debuggers. Step-Into and Step-Return: To debug a method , you need to use „Step-Into“ to step into the first statement of the method. You could use „Step-Return“ to return back to the caller, anywhere within the method. Alternatively, you could set a breakpoint inside a method.
Modify the Value of a Variable: You can modify the value of a variable by entering a new value in the „Variable“ panel. This is handy for temporarily modifying the behavior of a program, without changing the source code.

If you use the URL to read an audio or Image files, then place the files under “ src “ instead of the project base directory , which will be copied into the “ bin “ directory.
For Servlet 2. You can debug a webapp just like standalone application.

If the „Welcome“ screen shows up, close it by clicking the „close“ button next to the „Welcome“ title. Step 1: Create a new „Java Project“ For each Java application, you need to create a project to keep all the source files, classes and relevant resources.
The „New Java Project“ dialog pops up. In „Project name“, enter “ FirstProject „. Check „Use default location“. Make sure that your JDK is 11 and above.
In „Project Layout“, check „Use project folder as root for sources and class files“. Push „Finish“ button. IF „Create module-info. The „New Java Class“ dialog pops up. In „Source folder“, keep the „FirstProject“. If the Eclipse Foundation is the Publisher, you are good to select Run.
