运行结果
考试平均分:78.5
调整后的平均分:83
性别:男
68.3

package com.imooc; public class Demo02{ public static void main(String[] args) { double avg1=78.5; int age3= (int) 68.3; char sex='男'; boolean close=true; int rise=5; int avg2=(int)avg1+rise; double age4=avg1+age3; System.out.println("考试平均分:"+avg1); System.out.println("调整后的平均分:"+avg2); System.out.println("性别:"+sex); System.out.println(age3); System.out.println(age4); System.out.println("确认关闭吗:"+close); } }
float的问题,在后面age4里应该是因为avg1+(float)age3才出错
