Question

ios 数组的set方法什么时候执行

Answer 1

package com.knowhowinfo;import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.method;public class Test {
public static void main(String args[]) throws IllegalArgumentException, IllegalAccessException, InvocationTargetException, InstantiationException, SecurityException, NoSuchmethodException {
Class<A> c = A.class;
//返回所有的方法
method[] ms = c.getDeclaredmethods();
A a = c.newInstance();
for (method method : ms) {
//这里遍历一下 可有可以无 实验而已
System.out.println(method);
}
method m = c.getDeclaredmethod("set", int.class,String.class);
m.setAccessible(true);//因为写成private 所以这里必须设置
m.invoke(a, 5,"你好");

}
}
class A{
private void set(int i,String s){
System.out.println(i+","+s);
};
}
