• How do I print the method body reflectively? 3 answers

I want get all content code of method (System.out.println("foo1"); and System.out.println("foo2"); in may case) but I do not find?

import java.lang.reflect.Method;

public class DisplayMethod {

    public static void main(String[] args) {
        final Method[] methods = DisplayMethod.class.getDeclaredMethods();
        for (final Method method : methods) {
            System.out.println(method.getName() + " " + method.toGenericString());
        }
    }

    private void foo1() {
        System.out.println("foo1");
    }

    private void foo2() {
        System.out.println("foo2");
    }

}

actual result:

main public static void sof.DisplayMethod.main(java.lang.String[])
foo1 private void sof.DisplayMethod.foo1()
foo2 private void sof.DisplayMethod.foo2()

target result:

foo1  private void sof.DisplayMethod.foo1() { System.out.println("foo1"); }
foo2  private void sof.DisplayMethod.foo2() { System.out.println("foo2"); }
