JAVA 编写一个程序完成从某账户取款和存款的操作
(1)输入存款金额是,如果非数值型,捕获一场并进行处理
(2)操作账户类是,如果取款金额大于余额时则做异常处理
import java.util.Scanner;
public class Blank {
public static void main(String[] args) {
float residue = 10000.0f;
String type;
Scanner scn = new Scanner(System.in);
while(true) {
System.out.println("****当前账户余额:"+residue+"****");
System.out.println("1.存钱 2.取钱 0.退出");
System.out.print("请选择(1,2,0):");
type = scn.nextLine();
if(type.equals("1")) {
System.out.print("请输入金额:");
try {
int money = scn.nextInt();
residue = money+residue;
} catch (Exception e) {
// TODO: handle exception
System.out.println("输入错误...");
scn.nextLine();
}
}
else if(type.equals("2")) {
try {
System.out.print("请输入:");
int money = scn.nextInt();
if(money>residue) {
throw new Exception();
} else {
residue = residue-money;
}
} catch (Exception e) {
// TODO: handle exception
System.out.println("余额不足");
scn.nextLine();
}
}
else if(type.equals("0")) {
System.out.println("bye..");
break;
}
}
}
}
