Simple Java calculator
- by Kevin Duke
Firstly this is not a homework question. I am practicing my knowledge on java. I figured a good way to do this is to write a simple program without help. Unfortunately, my compiler is telling me errors I don't know how to fix. Without changing much logic and code, could someone kindly point out where some of my errors are? Thanks
import java.lang.*;
import java.util.*;
public class Calculator
{
private int solution;
private int x;
private int y;
private char operators;
public Calculator()
{
solution = 0;
Scanner operators = new Scanner(System.in);
Scanner operands = new Scanner(System.in);
}
public int addition(int x, int y)
{
return x + y;
}
public int subtraction(int x, int y)
{
return x - y;
}
public int multiplication(int x, int y)
{
return x * y;
}
public int division(int x, int y)
{
solution = x / y;
return solution;
}
public void main (String[] args)
{
System.out.println("What operation? ('+', '-', '*', '/')");
System.out.println("Insert 2 numbers to be subtracted");
System.out.println("operand 1: ");
x = operands;
System.out.println("operand 2: ");
y = operands.next();
switch(operators)
{
case('+'):
addition(operands);
operands.next();
break;
case('-'):
subtraction(operands);
operands.next();
break;
case('*'):
multiplication(operands);
operands.next();
break;
case('/'):
division(operands);
operands.next();
break;
}
}
}
