java随机生成10个整数，打印出其最大值、最小值、平均值。

public class Intnumber {
    //新建一个包含十个数的数组a
    static int a[]=new int[10];
    //方法number生成10个随机数
    void number(){
        for(int i=0;i<10;i++){
            a[i]=(int)(Math.random()*1000);
        }
    }
    //方法maxnum获取数组最大值
    int maxnum(){
        int max=a[0];
        for(int i=0;iif(a[i]>max){
                max=a[i];
            }
        }
        return max;
    }
    //方法minnum获取数组最小数值
    int minnum(){
        int min=a[0];
        for(int i=0;iif(a[i]return min;
    }
    //方法avgnum获取数组平均值
    int avgnum(){
        int avg,sum;
        sum=0;
        for(int i=0;ireturn avg;
    }
    //方法pringing打印数组
    void printing(){
        for(int i=0;iout.print(a[i]+"   ");
        }
    }
    public static void main(String args[]){
        Intnumber stern=new Intnumber();
        stern.number();
        stern.printing();
        System.out.println();
        System.out.println("the max number is "+stern.maxnum());
        System.out.println("the min number is "+stern.minnum());
        System.out.println("the avg number is "+stern.avgnum());
    }
