Javac clear - Java

Introduction

Javac clear is a command used in Java to clear the compiled class files generated by the javac command. The class files are generated when we compile the Java source code using the 'javac' command. Clearing the compiled class files will help you recompile the source code without any conflicts or issues.

Usage

To use 'javac clear' in your Java program, follow the steps below:

1. Open your command prompt or terminal.

2. Navigate to the directory where your Java files are located.

3. Type the following command to clear the compiled class files:

   javac -clear
   

4. Press enter to execute the command.

Example

Suppose we have a Java program named 'HelloWorld.java' and we compile it using the command 'javac HelloWorld.java'. This will generate a compiled class file named 'HelloWorld.class'. If we make any changes to the 'HelloWorld.java' file after compiling it, we need to clear the compiled class file before recompiling it.

We can use 'javac clear' command as follows to clear the compiled class file:

javac -clear HelloWorld.class

This will delete the 'HelloWorld.class' file, and we can recompile the Java program using the 'javac HelloWorld.java' command.

Conclusion

Javac clear command is a useful command in Java to clear the compiled class files generated by javac command. This helps us in recompiling the Java program without any issues or conflicts.
