How to solve the issue of array index out of bounds in Java?

In Java, the issue of array out of bounds can be solved in the following ways:

1. Avoid accessing index values that exceed the length of the array. When using arrays, make sure the index value does not exceed the length of the array minus one, or use looping to control the range of the index.
2. Catch array index out of bounds exception with try-catch statement. You can use a try-catch statement to catch the ArrayIndexOutOfBoundsException, and perform appropriate actions such as printing error messages or other operations when the exception is caught.

Sample code:

try {
    int[] array = new int[5];
    // 访问超出数组长度的索引值
    int value = array[6];
} catch (ArrayIndexOutOfBoundsException e) {
    System.out.println("数组越界异常：" + e.getMessage());
    // 或者进行其他处理
}

1. Check if the index value is out of bounds using an if statement. Before accessing the array element, you can use an if statement to determine if the index value is within the legal range. If it is not within the range, do not access the array element or perform other actions.

Sample code:

int[] array = new int[5];
int index = 6;
// 判断索引值是否越界
if (index >= 0 && index < array.length) {
    int value = array[index];
} else {
    System.out.println("索引值越界");
    // 或者进行其他处理
}

The Java array index out of bounds issue can be effectively addressed using the above methods.
