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
