Java怎么實(shí)現(xiàn)銀行存取款功能

本篇內(nèi)容介紹了“Java怎么實(shí)現(xiàn)銀行存取款功能”的有關(guān)知識(shí)，在實(shí)際案例的操作過(guò)程中，不少人都會(huì)遇到這樣的困境，接下來(lái)就讓小編帶領(lǐng)大家學(xué)習(xí)一下如何處理這些情況吧！希望大家仔細(xì)閱讀，能夠?qū)W有所成！

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(shí)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();  }}
