When we compile a java code the .class file is created in the same place where the source code is . Is there a way like when we compile a java code the .class file file will be formed in a different folder

I tried creating projects and then writing the code but it didn't work

CodePudding user response：

Yes there is. When you compile your java file with

javac file.java

This default stores .class of that file in same folder.

To store .class in different folder use -d paramter with javac as:

javac file.java -d "Path"

For ex:

javac file.java -d "D:/Classes"

Then while running the files you have to set classpath so that JVM will search class files in that folder:

java -classpath "D:/Classes" file

FYI: If your file name is say Test.java and when you run javac, Test.class gets created at the path mentioned.

You can change the path where your .class is created following the next steps:

• File -> Preferences ->Settings
• Write java.output on the search bar and it should show you "Java > Project : Output Path.
• Click on edit in setting.json and write the new path where you want your .class to be generated.

Do you compile manually with command line javac ? If so you can make a bash script (if you are on linux) that move all class file to another directory after compilation.

Something like:

mv *.class destination/

I think you have similar command on windows.

In vscode you can can then configure your launch.json to execute that command as well as the compilation one.
