我想在这个frame中加入一个控制到时提醒的程序，该怎么加？我这写的是一个备忘录，要实现备忘到时提醒，该怎么弄？

Answer 1

线程不会，不 是有个Timer类吗？加那个该怎么加呢？

Answer 3

靠，用代码还不显示红色，那自己对这找一下吧
//以下四行，现记录当前程序启动时的时间，然后启动线程
        long oldTime = System.currentTimeMillis();
        CountTime ct = new CountTime( oldTime );
        //System.out.println( oldTime );
        ct.start();    
} 
//以下的多线程类，实现时间计算功能
class CountTime extends Thread
{
    long oldTime = 0;
    
    CountTime( long oldTime )
    {
        this.oldTime = oldTime;
    }
    
    public void run()
    {
        while(true)
        {
            //get recent system time
            long newTime = System.currentTimeMillis();
            //System.out.println( newTime );
            
            if( newTime - this.oldTime >= 10000 )
            {
                JOptionPane.showMessageDialog( new Frame(), "TIME OUT" );
                System.exit( 0 );
            }
        }
    }
}
