What does index beyond array range mean?

The index beyond the range of the array means that when obtaining the value in the array through the index, the index exceeds the total length of the array. There are 10 elements in the array Array, its total length is 10, and the index is [0- 9], if the index is 10, an error will be reported.

IndexExceeding the array limit means that when obtaining the value in the array through the index, the index exceeds the total length of the array.

For example:

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

There are 10 elements in this int array Array, its total length is 10, and its index is 0-9.

When using a for loop to obtain the value in the array, if the index is 10, an error will be reported. The reason for the error is that

the index exceeds the array limit.

for(int i=0;i<11;i++) {
System. out .println( String. format(“ 第%d元素的值是%\n",i+1 ,Array[i]));
}

Characteristics of arrays:

1. Arrays contain elements of the same data type gather.

2. The elements in the array are stored in order, and they are stored continuously in the memory in this order.

3. The array element is represented by the name of the entire array and its sequential position in the array. For example, a[0] represents the first element in the array named a, a[1] represents the second element of the array a, and so on.
