Information can be passed to methods as a parameter. Parameters act as variables inside the method.Parameters are specified after the method name, inside the parentheses. You can add as many parameters as you want, just separate them with a comma....

If a method is created with parameters, we need to pass the corresponding values while calling the method. For example, // calling the method with two parameters addNumbers(25, 15); // calling the method with no parameters addNumbers() Example 3: Method Parameters class Main { // method...

在框架中经常会会用到method.invoke()方法,用来执行某个的对象的目标方法。以前写代码用到反射时,总是获取先获取Method,然后传入对应的Class实例对象执行方法。然而前段时间研究invoke方法时,发现invoke方法居然包含多态的特性,这是以前没有考虑过的一个问题。那么Method.invoke()方法的执行过程是怎么实现的?它的多态又...
