Question

Java Programming

In this assignment we are going to create our own programming language, and process it Java.

programming language has 6 commands

1. enter
2. add
3. subtract
4. multiply
5. divide
6. return

enter, add, subtract, multiply, divide all take 1 parameter (a double value).

return takes no parameters.

Answer 1

import java.util.Scanner;
public class Main
{
   public static void main(String args[])
   {
       int x = 0;
        Scanner s = new Scanner(System.in); //Scanner class for Taking input

       public int enter(double x)
        {
System.out.println("Enter the number to perform operations ");
System.out.print("Enter the number : ");
x = s.nextInt();
return x;
}

while(true){
            System.out.println("Choose the operation you want to perform ");
            System.out.println("Choose 1 for ADDITION");
            System.out.println("Choose 2 for SUBTRACTION");
            System.out.println("Choose 3 for MULTIPLICATION");
            System.out.println("Choose 4 for DIVISION");
            System.out.println("Choose 5 for Return");

            int n = s.nextInt();
            switch(n)
            {
                case 1:
int x = enter(1);
void add(double x){
                  System.out.println(x+x);
}
break;

                case 2:
int x = enter(1);
void sub(double x){
                   System.out.println(x-x);
}
break;

                case 3:
               int x = enter(1);
                void mul(double x){
                 System.out.println(x*x);
                }
                break;

                case 4:
               int x = enter(1);
                void div(double x){
                  System.out.println(x+x);
               }

                break;

                case 5:
                 return;
               default:
break;
}
               System.out.println("do you want to continue y/n");

char l=in.next().charAt(0)

if(l!='y')
{
   break;
}

}
    }
}
