這篇文章主要為大家詳細介紹了Java實現(xiàn)銀行存取款，文中示例代碼介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了Java銀行存取款的具體代碼，供大家參考，具體內(nèi)容如下

1.不加鎖情況

運行結(jié)果：

代碼：將加鎖情況中加鎖部分進行注釋即可

2.加鎖情況

運行結(jié)果

緩沖區(qū)代碼

package Bank;
 
import java.util.LinkedList;
 
public class BankAccount {
 static double sum=1000;
 
 private LinkedList<Object> list = new LinkedList<>();
 //存款
 public void deposit() {
 synchronized(list)
 {
 System.out.print(list.size());
 while(list.size()>1) {
 
 System.out.println("暫不支持存款");
 try {
  // System.out.print("wait");
  list.wait();
 } catch (InterruptedException e) {
  e.printStackTrace();
  //System.out.print("wait");
    }
 }
 list.add(new Object());
  int money=300;
 sum=sum+money;
 System.out.println(Thread.currentThread().getName()+"存入了"+money+"元"+"現(xiàn)在共有存款"+sum);
   list.notifyAll();
 }
 }
 //取款
 public void withdrawal() {
 synchronized(list)
 {
 while(list.size()==0) {
// int money=50;
// sum=sum-money;
 System.out.println(Thread.currentThread().getName()+"暫時不支持取款");
 try {
  list.wait();
 } catch (InterruptedException e) {
  e.printStackTrace();
 }
 }
 list.remove();
 int money=200;
 if(sum>200)
 {
 sum=sum-money;
 System.out.println(Thread.currentThread().getName()+"取出了"+money+"元"+"現(xiàn)在共有存款"+sum);
 }else {
 System.out.println("賬戶余額不足");
 }
 list.notify();
 
 }
 }
 
}

存款代碼

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();
 }
 }
 }
}

取款代碼

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();
 }
 }
 }
}

主函數(shù)代碼

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();
 
 }
}
