Example
The following example shows the usage of java.lang.Compiler.compileClass() method.
package com.tutorialspoint; import java.lang.*; public class CompilerDemo { public static void main(String[] args) { CompilerDemo cls = new CompilerDemo(); CompilerDemo subcls = new SubClass1(); // class CompilerDemo Class c = cls.getClass(); System.out.println(c); // sub class SubClass1 Class c1 = subcls.getClass(); System.out.println(c1); /* returns false if the compilation failed or no compiler is available */ boolean retval = Compiler.compileClass(c1); System.out.println("Return Value = " + retval); } } class SubClass1 extends CompilerDemo { // sub class }
Let us compile and run the above program, this will produce the following result −
class com.tutorialspoint.CompilerDemo class com.tutorialspoint.SubClass1 Return Value = false
