Java Program to check if a number is Neon or not
In this Java tutorial, we will learn how to check if a number is 'Neon' number or not. A 'Neon' number is a number whose sum of all digits of square of the number is equal to the number. For example, '9' is a Neon number. Because, square of 9 is 9*9= 81. Sum of all digits of 81 is 8+1=9. So it is a Neon number. Similarly 1 is also a Neon number. But 8 is not.

ReadJava program to remove element from an ArrayList of a specific index
In this program, we will learn how to remove an element of a specific index from an ArrayList. First, we will take 'n' number of inputs from the user . Next we will get the index of the number to be removed. To remove an element from a ArrayList, we can use 'remove(index)' method. 'index' is the index number. If the index is available, we will remove that number , otherwise we will ask the user for a valid input.
