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;
            }
        }
        
    }
}
