How can i resolve 'arrayindexoutofboundsexception in java'?

Example:

int[] arr = {1, 2, 3};
int value = arr[3];

Solution:

This error occurs when you try to access an array index that does not exist. Always check if the index is within the range of the array length.

int[] arr = {1, 2, 3};
if(arr.length > 3) {
    int value = arr[3];
}
