  • 1. 10 tips on debugging java program in Eclipse – Part 1 Debugging in Eclipse is real fun , come join me to explore great feature of eclipse.
  • 2. How to debug java program
    • Create a Java Project
    • Put a break point by double clicking on any line.
    • Right click and “Debug as Java Program”
    • Now it will start debugger and program will stop when control reach your breakpoint and it this point you can see values of variables, thread and evaluate express, check call stack to identify the bug.
  • 3. Java debugging in Eclipse Tip - 1
    • Use conditional breakpoint
    • Condition breakpoint is a breakpoint with condition and your thread will only stop at specified line if condition matches instead of just stopping on that line like in case of line breakpoint.
    • To setup a conditional breakpoint just double click on any line where you want to setup a breakpoint and then right click --> properties and then insert the condition. Now program will only stop when that particular condition is true and program is running on debug mode.
  • 4. Java debugging in Eclipse Tip - 2
    • Use Exception breakpoint
    • How many times you have frustrated with a NullPointerException and you don't know the source from where the exception is coming. Exception breakpoints are just made for such situation.
    • Both Eclipse and Netbeans allows you to setup Exception breakpoint. You can setup Exception breakpoint based on java exception like NullPointerException or ArrayIndexOutOfBoundException. You can setup Exception breakpoint from breakpoint window and your program will stop when you start it on debug mode and exception occurs.
  • 5. Java debugging in Eclipse Tip - 3
    • Step over and Step into
    • These are simply great debugging options available in any Java IDE, extremely useful if you are debugging multi-threaded application and want to navigate step by step.
  • 6. Java debugging in Eclipse Tip - 4
    • Stopping for a particular Thread
    • This is my own custom made java debugging tips which I made using conditional breakpoints.
    • since most of my projects are multi-threaded java programs and I want only a particular thread to stop on a particular line, for doing that I setup a conditional breakpoint on that line and put Thread.currentThread().getName().equals("TestingThread") and it works fantastically.
  • 7. Java debugging in Eclipse Tip - 5
    • Inspect and Watch
    • These are two menu options which I use to see the value of expression during debugging java program.
    • I just select the statement, right click and inspect and it will show you the value of that statement at debugging time. You can also put watch on that and that condition and its value will appear on watch window.
