Sample code to programmatically compile a Java program.

public class CompilerExample {

        String fileToCompile = "c:" + java.io.File.separator
                + "HelloWorld.java";
        JavaCompiler compiler =      ToolProvider.getSystemJavaCompiler();
        int compilationResult = compiler.run(null, null, null, fileToCompile);
        if (compilationResult == 0) {
            System.out.println("Compilation is successful");
        } else {
            System.out.println("Compilation Failed");
