Using the -target release option we can do this, for example: javac -target 1.6 -source 1.5 MyProgram.java class files for a specific Java virtual machine (VM) version. That will tell the compiler using specific language features in Java 1.5 to compile the source file. For example: javac -source 1.5 MyProgram.java We can tell the compiler which Java version applied for the source file, by using the -source release option. Specify Java source compatibility version That will compile the MyProgram.java file in the src directory. For example: javac -sourcepath src MyProgram.java We can tell the compiler where to search for the source files by using the -sourcepath directoryoption.
