代码如下：
public static void main(String[] args) {
// TODO Auto-generated method stub
// 给数组赋值随机数
int arr[] = new int[10];
for (int i = 0; i < arr.length; i++) {
arr[i] = (int) (Math.random() * 100);
}
// 输出数组的值
for (int i = 0; i < arr.length; i++) {
System.out.println("数组的值为:" + i + ":" + arr[i]);
}
// 找出最大值
int max = arr[0];
for (int i = 1; i < arr.length; i++) {//i=0是自己和自己比
if (arr[i] > max) {
max = arr[i];
}
}
System.out.println("最大值为："+max);
//找最小值
int min=arr[0];
for (int i = 1; i < arr.length; i++) {
if(arr[i]<min) {
min=arr[i];
}
}
System.out.println("最小值为："+min);
//排序，把数组从小到大排序
System.out.println("排序前");
for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i]+" ");
}
System.out.println();
ArraySort(arr);//排序
System.out.println("排序后：");
for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i]+" ");
}
}
private static void ArraySort(int[] arr) {
// TODO Auto-generated method stub
//冒泡排序
for (int i = 0; i < arr.length-1; i++) {
for (int j = 0; j < arr.length-i-1; j++) {
if(arr[j]>arr[j+1]) {
int temp=arr[j];
arr[j]=arr[j+1];
arr[j+1]=temp;
}
}
}
}
}
