- 模拟银行账户业务
创建包bank.com，
编写Account类，添加带参
方法实现存款和取款业务，
存款时帐户初始金额为0元，
取款时如果余额不足给出提示
int chushi=0;
public int yewu(int y,int c)
{
if (y==1){
chushi=chushi+c;
System.out.println("存款成功");
System.out.println("当前余额为"+chushi);
}
return chushi;
}
public int yewu2(int y,int c)
{
if (y==2){
chushi=chushi-c;
if (chushi<=0){
System.out.println("余额不足");
}
else {
System.out.println("取款成功");
System.out.println("当前余额为" + chushi);
}
}
return chushi;
}
public int yewu3(int y)
{
if (y==0){
System.out.println("谢谢使用");
}
return chushi;
}
Account a = new Account();
Scanner scanner = new Scanner(System.in);
System.out.println("1.存款"+"2.取款"+"0.退出");
for (int i=0;i >-1;i++) {
System.out.println("请输入你选择的业务");
int s = scanner.nextInt();
if (s == 2) {
System.out.println("请输入取款金额");
int q = scanner.nextInt();
a.yewu2(s, q);
}
else if (s==0){
a.yewu3(s);
break;
}
else {
System.out.println("请输入存款金额");
int j = scanner.nextInt();
a.yewu(s, j);
}
