package com.main;
仅供楼主参考
public class test {

/**
* @param args
*/
public static void main(String[] args) {
final Bank bank = new Bank();
for(int i = 0; i<10; i++){
new Thread(new Runnable(
){
public void run() {
// TODO Auto-generated method stub
bank.deposit(100);

}
}).start();
new Thread(new Runnable(){
@Override
public void run() {
// TODO Auto-generated method stub
bank.withdraw(100);

}
}).start();

}

}

}
class Bank{
private int total = 1000;

public synchronized void deposit(int num){
total = total +num;
System.out.println("我是存线程"+Thread.currentThread().getName()+"存入了100元");
System.out.println("此时账户余额为:"+total);

}
public synchronized void withdraw(int num){
total = total - num;
System.out.println("我是取线程"+Thread.currentThread().getName()+"存入了100元");
System.out.println("此时账户余额为:"+total);
}

}
