怎么通过JTextField输入的值作为参数构建对象

Question

我是想通过一个按钮的mouseListerner 中的clickEvent 方法中 利用前面所定义的JTextField中输入的值构建新的对象。但是总也不能通过。
提示是找不到构造方法所要的参数。
请各位救我一命，实验做到这里没办法下去了。
先谢过了。

Answer 2

public void thread()
        {}
        public void thread(String pid,int Runtime,int priority,int statu)
        {
                this.pid=pid;
                this.rtime=rtime;
                this.priority=priority;
                this.statu=statu;
                }
这2个都不是构造函数
构造函数没有返回值

Answer 3

Object obj = Class.forName(jTextField1.getText()).newInstance();
