Java Code for Smallest And Largest of Three Integer

             Write a program that will ask the user to input three integer values from the keyboard. Then it will print the smallest and largest of those numbers. 

Code Here :

public static void main(String[] args) {

        int Num1, Num2, Num3, Maxi=0, Mini = 0;

        Scanner In = new Scanner(System.in);

        System.out.print("Enter Three Interger Number: ");

        Num1 = In.nextInt();

        Num2 = In.nextInt();

        Num3 = In.nextInt();

        if (Num1 > Num2 && Num1 > Num3 ) 

            Maxi = Num1;

        else if (Num2 > Num1 && Num2 > Num3)

            Maxi = Num2;

        else if (Num3 > Num1 && Num3 > Num2) 

            Maxi = Num3;

        if(Num1 <Num2 && Num1 < Num3)

            Mini = Num1;

        else if (Num2 < Num1 && Num2 < Num3)

            Mini = Num2;

        else if (Num3 < Num1 && Num3 < Num2)

            Mini = Num3;

Java Code for Display the calculator menu

               Write a program that will display the calculator menu. The program will prompt the user to choose the operation choice (from 1 to 5). Then it asks the user to input two integer vales for the calculation. See the sample below.

Code Here :

 public static void main(String[] args) {

        int Num1, Num2, op, Result = 0;

        char ch;

        do {

            Scanner In = new Scanner(System.in);

            System.out.println("MAIN MENU");

            System.out.println("1.Add");

            System.out.println("2.Subtract");

            System.out.println("3.Multipy");

            System.out.println("4.Divide");

            System.out.println("5.Mudulus");

            System.out.println(" ");

            System.out.print("Enter Yours Choice: ");

            op = In.nextInt();

            System.out.print("Enter Your Two Number: ");

            Num1 = In.nextInt();

            Num2 = In.nextInt();

            switch (op) {

                case 1:

                    Result = Num1 + Num2;

                    break;

                case 2:

                    Result = Num1 - Num2;

                    break;

                case 3:

                    Result = Num1 * Num2;

                    break;

                case 4:

                    Result = Num1 / Num2;

                    break;

                case 5:

                    Result = Num1 % Num2;

                    break;

                default:

                    System.out.println("You're Enter in Wrong Operator");

            }

            System.out.println("Your Result is: " + Result);

            System.out.println(" ");

            System.out.print("Do you want to calculate agian ? : [Y/N] ");

            ch = In.next().charAt(0);

        }while(ch=='y' || ch=='Y');

        

    }

}
