methoddemo.java

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 demo{
	public static void main (String[] args) {
	try {
		Class cc=Class.forName("student");
		Object o=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(o,new Object[]{null});	
			}
		}
    student ss=(student)o;
    System.out.println (ss.getName());
}
catch (Exception ex) {
}	
		
}
}
