When You write your codes for the program in using the JAVA high level programmming language you need a JAVA compiler in your computer to compile your codes in Java. if you have the C compiler you try a program I wrote below.
/* A PROGRAM TO CALCULATE TWO NUMBERS */
#include<stdio.h>
int main(void)
{
int a , b , sum;
printf("ADDITION OF TWO NUMBERS\N");
printf("enter a, a="); scanf("%d", &a);
printf("enter b, b="); scanf("%d", &b);
sum = a+b;
printf("sum=%d", sum);
return 0;
Then compile the program and run it as an executable file. I Will prepare you some notes in JAVA, Pascal and C.
end.

In java it's way more simple
import System.util.Scanner;
Scanner scan = new Scanner(System.in);
System.out.println("Kindly enter a number");
double a = (double)scan.next();
System.out.println("Kindly enter another number");
double b = (double)scan.next();
System.out.println ("enter 1, to add, 2 to sub etc...)
int x=scan.nextInt();
if (x==1)
System.out.println(a + " + " + b + " = " + x);
if (x==2)
System.out.println(a + " - " + b + " = " + x);
you can surrond that with a while function to start again after it finishes, and you can add as many variables you like...now that's a very simple calculator that doesn't uses a GUI
