如何用Java線程實(shí)現(xiàn)銀行的存款取款問題最好能寫出編出的具體程序

AccountTest.java class BankAccount //定義銀行賬戶類BankAccount{private static int amount =2000; //賬戶余額最初為2000public void despoit(int m) //定義存款的方法{amount=amount+m;System.out.println("曉明存入["+m+"元]");}public void withdraw(int m) //定義取款的方法{amount=amount-m;System.out.println("張新取走["+m+"元]");if(amount0)System.out.println("***余額不足！***)；public int balance() //定義得到賬戶余額的方法{return amount;}}classicCustomerextendsThread {String name;BankAccount bs; //定義一個(gè)具體的賬戶對(duì)象public Customer(BankAccount b,String s){name=s;bs=b;}public static void cus(String name,BankAccount bs) //具體的賬戶操作方法{if(name.equals("小明")) //判斷用戶是不是小明{try{for(int i=0;i6;i++) //用戶曉明則向銀行存款6次，每次1000元 {Thread.currentThread().sleep((int)(Math.random()*300));bs.despoit(1000);}}catch(InterruptedException e){}}else{try{for(int i=0;i6;i++) //用戶不是小明則從銀行取款6次，每次1000元{Thread.currentThread().sleep((int)(Math.random()*300));bs.withdraw(1000); }}catch(InterruptedException e){} }}public void run() //定義run方法}cus(name,bs); }}public classAccountTest{public static void main(String [] args) throws InterruptedException{BankAccount bs=new BankAccount();Customer customer1=new Customer(bs,"小明");Customer customer2=new Customer(bs,"張新");Thread t1=new Thread(customer1);Thread t2=new Thread(customer2);t1.Start（）；t2.start();Thread.currentThread().sleep(500);}}

用java線程同步實(shí)現(xiàn)銀行取款和存款。

你的代碼問題很多！

幫你修改后：

class Account {

private static float Balance = 200f;//線程共享的錢

public synchronized static void deposit(float amt) {

Balance = Balance + amt;

try {

Thread.sleep(10);// 模擬其它處理所需要的時(shí)間，比如刷新數(shù)據(jù)庫等

}

catch (InterruptedException e) {

}

}

public static float getBalance() {

return Balance;

}

public static void setBalance(float balance) {

Balance = balance;

}

public synchronized static void withdraw(float bmt) {

Balance -= bmt;

try {

Thread.sleep(10);// 模擬其它處理所需要的時(shí)間，比如刷新數(shù)據(jù)庫等

}

catch (InterruptedException e) {

}

}

String name;

public Account(String name) {

this.name = name;

}

}

public class AccountTest {

public static void main(String[] args) {

Customer customerA = new Customer("A");

Customer customerB = new Customer("B");

customerA.start();

customerB.start();

System.out.println();

try {

customerA.join();//等待A線程執(zhí)行完畢

customerB.join();//等待B線程執(zhí)行完畢

}

catch (InterruptedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

System.out.println("最后總錢數(shù):" + Account.getBalance());

}

}

class Customer extends Thread {

public Customer(String string) {

super(string);

}

@Override

public void run() {

System.out.println(currentThread().getName());

if (currentThread().getName().equals("A"))

Account.deposit(100.0f);//A線程加100

else if (currentThread().getName().equals("B"))

Account.withdraw(50.0f);//B線程減50

}

}

用java語言編寫一個(gè)小型的銀行系統(tǒng)代碼

private?int?balance?=?0;

private??String?username?=?"A";

private??String?password?=?"B";

public?void?bank()?{

Scanner?scan?=?new?Scanner(System.in);

String??temp;

while?(true)?{

System.out.println("輸入賬號(hào)：");

if?(scan.hasNext())?{

temp?=?scan.next();

if?(temp.equals(username))?{

break;

}?else?{

System.out.println("輸入錯(cuò)誤");

}

}

}

while?(true)?{

System.out.println("輸入密碼：");

if?(scan.hasNext())?{

temp?=?scan.next();

if?(temp.equals(password))?{

break;

}?else?{

System.out.println("輸入錯(cuò)誤");

}

}

}

System.out.println("登錄成功");

while?(true)?{

System.out.println("輸入操作：");

if?(scan.hasNext())?{

temp?=?scan.next();

switch?(temp)?{

case?"存款":

int?x?=?0;

while?(true)?{

System.out.println("輸入存款金額：");

if?(scan.hasNextInt())?{

x?=?scan.nextInt();

break;

}?else?{

System.out.println("輸入錯(cuò)誤");

scan.next();

}

}

balance?+=?x;

break;

case?"取款":

int?y?=?0;

while?(true)?{

System.out.println("輸入取款金額：");

if?(scan.hasNextInt())?{

y?=?scan.nextInt();

if?(balance??y)?{

System.out.println("余額不足");

continue;

}

break;

}?else?{

System.out.println("輸入錯(cuò)誤");

scan.next();

}

}

balance?-=?y;

break;

case?"余額":

System.out.println("余額："?+?balance);

break;

case?"終止":

System.exit(0);

default:

System.out.println("未知操作");

}

}

}
