debug

I cannot find much information on debugging a java class. Could sombody help me with this. Just the command, step through, break points and examine and to get line numbers would be sufficient. Greatly appreciated. Thanks

Use the JDB (Java DeBugger) tool. See the JDB Tool forum for info on how to use it.
