{
  public static void main(String args[])
  {
     int input1,digit;
     Scanner sc=new Scanner(System.in);
     System.out.println("Enter The Input:");

       {
          System.out.println("The Last Digit Is Not Divisible By 3.");
       }

  }

}

Program Explanation

1. Get input from user using scanner class

2.extract last digit from input1 using the expression digit=input1%10.

3. check whether the remainder of digit divided by 3 is equal to 0 using if statement.

    if it is 0, then

        3a. print digit is divisible by 3 using printf statement.

    Else

        3b. print digit is not divisible by 3 using system.out.println.
