存款代码
package Bank; public class Deposit implements Runnable { private BankAccount bankAccount1; public Deposit() {} public Deposit(BankAccount bankAccount1) { this.bankAccount1=bankAccount1; } @Override public void run() { // TODO Auto-generated method stub while(true) { try { Thread.sleep(2000); bankAccount1.deposit(); } catch (InterruptedException e) { // TODO: handle exception e.printStackTrace(); } } }}
取款代码
package Bank; public class Withdrawal implements Runnable{ private BankAccount bankAccount; public Withdrawal() {} public Withdrawal(BankAccount bankAccount) { this.bankAccount=bankAccount; } @Override public void run() { // TODO Auto-generated method stub while(true) { try { Thread.sleep(3000); bankAccount.withdrawal(); } catch (InterruptedException e) { // TODO: handle exception e.printStackTrace(); } } }}
主函数代码
package Bank; public class Main { public static void main(String[] args) { BankAccount bankAccount1=new BankAccount(); Thread d1=new Thread(new Deposit(bankAccount1)); Thread d2=new Thread(new Deposit(bankAccount1)); Thread d3=new Thread(new Deposit(bankAccount1)); Thread w1=new Thread(new Withdrawal(bankAccount1)); Thread w2=new Thread(new Withdrawal(bankAccount1)); Thread w3=new Thread(new Withdrawal(bankAccount1)); d1.start(); d2.start(); d3.start(); w1.start(); w2.start(); w3.start(); }}
