Answer with Explanation

If a program tries to access an element beyond the array’s size, Java will throw an ArrayIndexOutOfBoundsException.

Example:


public class Example {
    public static void main(String[] args) {
        int[] ints = new int[50];
        ints[60] = 12345;  // Error: index 60 doesn’t exist
    }
}

Output: 


Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException
    at Example.main(Example.java:4)
