In JDB, STEPPING is a procedure to EXECUTE the code LINE by line. Thus, through this approach each line of the code can be examined PROPERLY.

In JDB, Stepping is a procedure to execute the code line by line. Thus, through this approach each line of the code can be examined properly.

These are the FOLLOWING TECHNIQUES of STEPPING: -

• STEP Over
• Step Into
• Step RETURN

These are the following techniques of stepping: -

A breakpoint can be set EITHER on the basis of method name or specific number of line.

To set a breakpoint on method, the FOLLOWING syntax is USED: -

stop in CLASSNAME.MethodName

To set a breakpoint on specific line, the following syntax is used: -

stop at Classname:LineNumber

A breakpoint can be set either on the basis of method name or specific number of line.

To set a breakpoint on method, the following syntax is used: -

stop in Classname.MethodName

To set a breakpoint on specific line, the following syntax is used: -

stop at Classname:LineNumber

Breakpoints are used in debugging to PAUSE or stop the execution of a program at a SPECIFIC line of CODE and TEST whether the program is functioning correctly or not.

The PRINT command is USED to display the value of expressions whereas DUMP command is used to display the information of objects.

The print command is used to display the value of expressions whereas dump command is used to display the information of objects.

Use the FOLLOWING command to COMPLETE the partial EXECUTION of program: -

>cont

Use the following command to complete the partial execution of program: -

>cont

To START the execution of main CLASS you just need to execute the below command: -

>run [class [args]] 

It is optional to MENTION the name of SPECIFIC class and argument.

To start the execution of main class you just need to execute the below command: -

>run [class [args]] 

It is optional to mention the name of specific class and argument.

To debug an APPLET we have to execute the DEBUGGER within applet VIEWER by the help of following command: -

>APPLETVIEWER -debug URL

To debug an applet we have to execute the debugger within applet viewer by the help of following command: -

>appletviewer -debug URL

The following SYNTAX is required to INVOKE debugger: -

jdb [options] [CLASSNAME] [arguments]

The following syntax is required to invoke debugger: -

jdb [options] [classname] [arguments]

JAVA debugger INTERACTS with the Java RUNTIME interpreter to interrupt the normal flow of program. Thus, Java interpreter PROVIDES SUPPORT to debugger.

Java debugger interacts with the Java runtime interpreter to interrupt the normal flow of program. Thus, Java interpreter provides support to debugger.

There are VARIOUS WAYS to connect JDBC with JAVA but the simplest ONE is to PROVIDE the following command at the runtime of your main class:-

>jdbc Main Class

Various TYPES of APPROACHES USED for debugging are: -

• Optimized code debugging
• Using COMMENTS
• BASIC Java bytecode (by using System.out.println() )
• Remote Debugging
• Debugging on demand

Various types of approaches used for debugging are: -

These are some COMMONLY GENERATE bugs: -

Syntactic or Compilation errors - These errors are GENERALLY generated due to some typing mistakes.

Run-time errors - These errors are generated at execution time generally due to EXCEPTIONS.

Threading errors - These errors are difficult to replicate and track down.

These are some advantages of Java DEBUGGER: -

• It is a lightweight debugging tool.
• It is free to USE and AVAILABLE for all type of operating SYSTEMS.
• The execution of Java debugging tool is very fast.
• It provide support for MULTITHREADED programs and remote applications.

These are some advantages of Java Debugger: -

(JDB) Java debugger is a command LINE Java DEBUGGING tool used to debug Java programs without the requirement of INSERTING specific debugging INSTRUCTIONS into the code.
