Join Peggy Fisher for an in-depth discussion in this video Command line debugging, part of Java Essential Training for Students.
- If you're the type of programmer that prefers to use…the command line to run your programs,…we can still do debugging.…There is a command line debugger available within the jdk.…The debugger is called jdb, for Java Debugger.…The first thing we need to do when we're in…our command window is to make sure…that we still have our path set.…So I'm gonna use my batch file…and I'm gonna type SetPath.bat.…Now, it's a good idea to recompile your program…using the -g option.…
This generates all the debugging information.…So let's do that.…I'm gonna do javac.…Copy the exercise file for this video…to your myJava folder to follow along.…I have a program in my myJava folder called DebugDemo.java.…I'm gonna use the -g option.…Okay, now I'm ready to use the Java Debugger…that's included in our jdk environment.…So, to debug the program, we type in jdb.…
Then we type in the name of our class, DebugDemo.…And our particular program requires…that we pass in a message.…So I'm gonna say "Welcome to Lynda.com."…Now I need to specify the debug information.…
