How can I create a Java class file from a Java file from my program?

Suppose there is a Java file that exists in an external folder. Can I write a Java program which will generate a .class file of that Java file and place the .class file in the same external folder?

It's in here: java.lang.Compiler. This class has the method compileClass(Class class) and compileClasses(String names)

The easiest way (for me) is to include tools.jar and to invoke the com.sun.tools.javac.Main.compile() function.
