java - 为什么这个数组显示错误消息(Eclipse)

Question

int[] myArray = new int[] {1,2,3,4,5,6,7,8,9,10};        

for(int number : myArray) {
    System.out.println(myArray[number]);
}

这是输出:

2
3
4
5
6
7
8
9
10

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 10
    at javaPractice.selfAssignArrays.main(selfAssignArrays.java:10)

这是怎么回事？

Answer 1

您想要执行此操作:

for (int number : myArray) {
    System.out.println(number);
}

这相当于:

for (int i=0; i<myArray.length; i++)  {
    int number = myArray[i];
    System.out.println(number);
}
