How is array access performed in Java?

In Java, arrays are accessed through indexes. Array indexes start from 0, which represents the first element in the array. To access an element in an array, you need to use the array name followed by the index to retrieve the element at a specific position.

For example, suppose we have an integer array called intArray:

int[] intArray = {1, 2, 3, 4, 5};

To access the first element in an array, you can use the following syntax:

int firstElement = intArray[0];

This will assign the element at index 0 in the array (which is the first element) to the variable firstElement.

Similarly, to access other elements in the array, you can use the corresponding indexes. For example:

int thirdElement = intArray[2]; // 访问索引为2的元素（即第三个元素）

Please note that accessing elements beyond the array index range will result in an ArrayIndexOutOfBoundsException. Therefore, it is important to ensure that the index value is within the valid range before accessing array elements.
