this是个很巧妙地东西

递归引起堆栈异常。。。

package com.maozj.javatnk.tostring;

public class MyObj {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		MyObj mo = new MyObj("Alice");
		System.out.println(mo);
	}
	
	private String myName;
	
	public MyObj(String _myName){
		myName = _myName;
	}
	
	public String toString(){
		return "myName: "+myName+this;
	}

}
