我写的一个小程序,不知道为什么老是抛出数组越界的异常,请各位高手指正.
import java.lang.*;
public class ArrayTest{
  public static void main(String[] args)throws ArrayIndexOutOfBoundsException{
 int[] array=new int[]{1,2,6,7,5,2,8,4,6,7,9,11,5,3};
 boolean change=true;
 for(int i=1;i<=array.length&&change;i++){
  change=false;
  for(int j=i;j<=array.length-i;j++){
  int temp;
  if(array[j]>array[j+1]){
  temp=array[j];array[j]=array[j+1];array[j+1]=temp;
  change=true;
}
}
}System.out.println("最大值为:"+array[array.length]);
  System.out.println("最小值为:"+array[1]);
  float average;
  int sum=0;
for(int i=1;i<=array.length;i++){
  sum+=array[i];
}
average=sum/array.length;
System.out.println("平均值为:"+average);
System.out.println("和为:"+sum);
}}

------解决方案--------------------
下标从0开始,到Array.length-1结束
你的引用有问题了
Java code
public class Overloading {
    public static void main(String[] args)
            throws ArrayIndexOutOfBoundsException {
        int[] array = new int[] { 1, 2, 6, 7, 5, 2, 8, 4, 6, 7, 9, 11, 5, 3 };
        
        for (int i = 0; i < array.length-1 ; i++) {
            
            for (int j = i+1; j < array.length ; j++) {
                int temp;
                if (array[i] > array[i + 1]) {
                    temp = array[i];
                    array[i] = array[i + 1];
                    array[i + 1] = temp;
                    
                }
            }
        }
        System.out.println("最大值为:" + array[array.length-1]);
        System.out.println("最小值为:" + array[0]);
        float average;
        int sum = 0;
        for (int i = 0; i < array.length; i++) {
            sum += array[i];
        }
        average = sum / array.length;
        System.out.println("平均值为:" + average);
        System.out.println("和为:" + sum);
    }
}
