编辑一个兑换零钱的模板
public class ChangeDemo {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
//输入金额
System.out.print("请输入您需要兑换的面值");
int money = input.nextInt();
//定义了money的变量
int nub50 = 0, nub10 = 0, nub5 = 0, nub1 = 0;
nub50 = money / 50;
money %= 50;
nub10 = money / 10;
money %= 10;
nub5 = money / 5;
money %= 5;
//此时除五的余数就为剩余面额一元钞票所需的值
nub1 = money;
System.out.println("可兑换共计50元张数:" +nub50);
System.out.println("10元张数:"+nub10);
System.out.println("5元张数:"+nub5 );
System.out.println("1元张数:" +nub1);
}
}
银行年利率计算
import java.util.Scanner;

System.out.println("注，银行的年利率为5%");
System.out.print("请输入您的本金:");
Double money = input.nextDouble();
//开始计算
money *=0.025;
//输出金额
System.out.println("您账户的利息为"+money);
}
