Method Calls in Groovy Closure

Here is the example, to call methods from the Closure, at runTime
class MethodCallsInClosure {

    def call1(){
        println "Call 1";
    }
 
    def call2(){
        println "Call 2";
    }
    //A Closure
    def test(Closure c){
        c.delegate = this;
        c();
     
    }
 
    static void main(args){
        MethodCallsInClosure m = new MethodCallsInClosure();
        //invoking calls inside the Closure and pass to the methods
        m.test{m.call1(); m.call2()}
        m.test1{m.call1(); m.call2()}
    }
    //another way of Closure
    def test1 = {
        it.delegate = this;
        it.doCall();
        it();
    }

}

prints :

Call 1

Call 2

Call 1

Call 2

Call 1

Call 2
