关于取款问题 java同步简单的小例子

package abit;

public class RemoveMoney implements Runnable{
public static int mymoney=2000;
public static void main(String[] args){
RemoveMoney t=new RemoveMoney();
new Thread(t,"A").start();
new Thread(t,"B").start();
}

public void run() {
try{
Thread.sleep(1000);
}catch(Exception e){}
remove(1500);

}
public  synchronized void remove(int money){
if(mymoney>money){
mymoney-=money;
System.out.println(Thread.currentThread().getName()+"取走"+money+",剩下"+mymoney);
}else{
System.out.println(Thread.currentThread().getName()+"你的余额不足");
}

}
}

/*输出：

A取走1500,剩下500
B你的余额不足

*/
