Calculator

#1

Would it be possible to get the code (answer) for A Basic Calculator?
I am new a still having trouble. Thank you,

Here is my code. But I do belive, that without Scanner, it is pointless (allows user to add input);

public class Calculator {
  
    public Calculator ()//constructor
    {}

  
  
  public int add(int a, int b) //method add
      
  
{
return a + b; 
}
  
  public int substract(int a, int b) //method substract
      
  
{
return a - b; 
}
  
public int multiply(int a, int b) //method multiply
      
  
{
return a * b; 
}
  
public int divide(int a, int b) //method divide
      
  
{
  if (b == 0)
  {
    System.out.println("Error! Dividing by zero is not allowed.");
  return 0;
  }
  else
  {
return a / b; 
  }
    
}
  
public int modulo(int a, int b) //method modulo
      
  
{
if (b == 0)
  {
    System.out.println("Error! Dividing by zero is not allowed.");
  return 0;
  }
  else
  {
return a % b; 
  }
 
}
  
  public static void main(String[] args) {//main method
  Calculator myCalculator = new Calculator ();//object myCalc.
    System.out.println(myCalculator.add(5, 7));
    System.out.println(myCalculator.substract(45, 11));
  }
    
}

This really helped me get out of a jam.
Thanks!
