java写的一个反射的例子 大家看看 虽u然小 但能是说明问题

import java.lang.reflect.Method;
class Student{
    private String id="001";
	private String name="zjamgsan";
	private String addrss="wjuxi";
	public String getAddrss() {
		return addrss;
	}
	public void setAddrss(String addrss) {
		this.addrss = addrss;
	}
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}	
}
class test{
	public static void main (String[] args) {
		try{
			Class cc = Class.forName("Student");
    	    Object oo = cc.newInstance();
    	    Method[] methods = cc.getDeclaredMethods();
    	    for(int i = 0;i<methods.length;i++){
    	    String name = methods[i].getName();
    	    if(name.startsWith("set")){
    	    	methods[i].invoke(oo,new Object[]{null});
    	    }	
    	}
    	Student ss = (Student)oo;
    	System.out.println (ss.getName());
		}
    	catch(Exception e){
    	}
    	
    }
}
