In Java, array indexing starts with 0. This is because an array is a contiguous block of memory where each element occupies a fixed amount of space. It is the offset from the start of the array.
Consider the following code:
int[] arr = new int[5];
arr[0] = 10;
arr[1] = 20;
arr[2] = 30;
arr[3] = 40;
arr[4] = 50;
In this code, we declare an array of size five and assign values to each element. The index of the first element is coming 0, and the last element index is coming 4, which is the size of the array minus 1.
