Debug debugs Java programs
We can debug the Java program in the Package Explorer view as follows:
- Right-click the java class that contains the main function
- Select Debug As and Java Application
This can also be done with shortcuts, which are combined as Alt plus Shift plus D, J.
The above creates a new Debug Configuration (debug configuration) and uses that configuration to launch a Java app.
If Debug Configuration has been created, you can launch the Java app by selecting the appropriate class for Debug Configurations from the Run menu and clicking the Debug button.
The Debug menu item for the Run menu can be reloaded before using debug mode for java apps.
The java app shortcut that used debug mode before reloading is F11.
When the java program is turned on using debug mode, the user is prompted to switch to the debug perspective. Debug perspectives provide additional views for troubleshooting your application.
The java editor can set break point debugging. Right-click the marker bar in the editor and select Toggle Breakpoint to set breakpoint debugging.
Break points can be seen in the marker bar. You can also see it in Breakpoints View.
The JVM suspends the program when it executes code that is marked by a break point, and you can view memory usage and control program execution.
When the program hangs, the Debug (debug) view checks the call stack.
The variables view can see the value of the variable.
There are resume menu items in the Run menu, skip a line of Step Over code, go to a function, and so on.
The image above shows associated shortcut actions such as Resume, Step Into, and Step Over.
