Simple of Java Reflection

define an entityObject:

java 代码

class Employee {
    // 定义一个员工类
    public Employee() {
        age = 10;
        name = null;
    }
    // 将要被调用的方法
    public void setAge(int a) {
        age = a;
    }
    // 将要被调用的方法
    public int getAge() {
        return age;
    }
    // 将要被调用的方法
        public void printInfo(String name,int age){
        System.out.println("myName is:"+name+"  myAge is:"+age);
    }
    private int age;
    private String name;
}

Test  Codes:

java 代码

class ReflectTest{
    public static void main(String[] args){
        Employee emp=new Employee();
        Class c=emp.getClass();
        try{
            Method printInfo=c.getMethod("printInfo", new Class[]{String.class,int.class});
            Object[] args1=new Object[]{"zhuhaihua",23};
            printInfo.invoke(emp, args1);
        }catch(Exception e){
        }
    }
}

just copy two pieces of code into the IDE(just like Eclipse) then run the ReflectTest class,you will get the result:
    myName is:zhuhaihua  myAge is:23
