【项目】家庭收支记账软件

1.说明

把收入和支出拼接成一个字符串，每一次增加记录都拼接在后面。

2.实现

package com.pxk;
public class FamilyAccount {
public static void main(String[] args) {
boolean loopFlag = true;
String details = "收支\t账户金额\t\t收支金额\t说 明\n";
double balance = 10000; //初始金额
do {
System.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");
System.out.print("请选择(1-4)：");
char menuSelection = Utility.readMenuSelection();
switch (menuSelection){
case '1':
System.out.println("-----------------当前收支明细记录-----------------");
System.out.println(details);
System.out.println("--------------------------------------------------");
break;
case '2':
System.out.print("本次收入金额：");
int income = Utility.readNumber();
System.out.print("本次收入说明：");
String incomeDesc = Utility.readString();
balance+=income;
details+="收入\t" + balance + "\t\t" +
income + "\t\t" + incomeDesc + "\n";
System.out.println("---------------------登记完成---------------------");
break;
case '3':
System.out.print("本次支出金额：");
int spend = Utility.readNumber();
System.out.print("本次支出说明：");
String spendDesc = Utility.readString();
balance-=spend;
details+="支出\t" + balance + "\t\t" +
spend + "\t\t" + spendDesc + "\n";
System.out.println("---------------------登记完成---------------------");
break;
case '4':
System.out.println("确认是否退出（Y/N）：");
char exit = Utility.readConfirmSelection();
if (exit=='Y'){
loopFlag = false;
}
break;
}
}while (loopFlag);
}
}
