类的测试
package com.gem.demo.day05_practice;import java.util.Scanner;public class HomeTest {public static void main(String[] args) {// TODO Auto-generated method stubSystem.out.println(“—————–家庭收支记账软件—————– “);System.out.println(“1:收支明细”);System.out.println(“2:登记收入”);System.out.println(“3:登记支出”);System.out.println(“4:退出”);Scanner input = new Scanner(System.in);Home h = new Home();boolean flag =true;while(flag) {System.out.println(“请选择(1~4)”);int num = input .nextInt();switch(num) {case 1:h.printAll();break;case 2:System.out.print(“本次收入金额为：”);int income = input.nextInt();System.out.print(“本次收入说明为：”);String incomeDetail = input.next();h.setIncome(income);h.setIncomeDetail(incomeDetail);break;case 3:System.out.print(“本次支出金额为：”);int expend = input.nextInt();System.out.print(“本次支出说明为：”);String expendDetail = input.next();h.setExpend(expend);h.setExpendDetail(expendDetail);break;case 4:flag = false;break;default:System.out.println(“输入有误”);}}}}
目前想到这个方法，欢迎各位在评论下写下你的实现的链接，一起进步。
