NO interface, NO lib, NO Java 8 needed!

Just using Callable from java.util.concurrent

public static void superMethod(String simpleParam, Callable methodParam) {

    //call methodParam
    try {
        methodParam.call();

    } catch (Exception e) {
        e.printStackTrace();
    }
}

How to use it:

 superMethod("Hello world", new Callable() {
                public Void call() {
                    myParamMethod();
                    return null;
                }
            }
    );

Where myParamMethod() is our passed method as parameter (in this case methodParam).
