Java练习题02

问题：

编程求一个整数数组的最大值、最小值、平均值和所有元素的和。

代码：

public
class Page99{

    public
static
void main(String args[]){

        int NumArray[]=new
int[]{32,94,15,86,1533,-98,143,140,11,39,65};

        int Average = 0;

        int Sum = 0;

        for(int j = 0; j < NumArray.length; j++){

            for(int i = j; i < NumArray.length; i++){

                if(NumArray[j] >= NumArray[i]){

                    int t = NumArray[i];

                    NumArray[i] = NumArray[j];

                    NumArray[j] = t;

                }    

                

            }

        }

        

        for(int j = 0; j < NumArray.length; j++){

            Sum = NumArray[j] + Sum;

        }

        Average = Sum/(NumArray.length);

        System.out.print("最小值：");    

        System.out.println(NumArray[0]);

        System.out.print("最大值：");    

        System.out.println(NumArray[NumArray.length-1]);

        System.out.print("总
和：");    

        System.out.println(Sum);

        System.out.print("平均值：");    

        System.out.print(Average);

 

    }

};
