How to Set Destination of the Class File in Java?

In this article, Let’s learn How to Set Destination of the Class File in Java. Before that, let’s understand what is a class file. When we compile a java file, we get a class file. A Java class file is a file containing Java byte-code and having ” .class” extension that can be executed by JVM.

The java file is compiled using javac command as shown below.

javac filename.java

In general, when a java file is compiled the generated ” .class” file will also be saved in the same folder. In order to set the destination of .class file we use -d option while compiling the ” .java” file, as shown below:

javac filename.java -d "path to store the .class file"

Example: 

Source         : Gfg.java file in "/home/mayur/" directory
Destination     :"/home/mayur/folder" directory
Command        : javac Gfg.java -d "/home/mayur/folder"
