how to compile multiple file in java using single command

Some times we need to compile multiple files with a single command. Though most programmer use IDe but sometimes we have command lines only.

If your case is like that then you can use any of the following methods-

1. Specify all the files manually

javac File1.java File2.java File3.java

2. Compile all .java file in the directory

javac *.java

This will compile all the Java files in the current directory.
