A lame calc | and a question about char's

Code:

//*Z0mg its a*//
//*Calculat0r*//
import java.util.Scanner;
public class Calculator
{
   public static void main(String[]args)
  {
   int num1;
  int num2;
  int calc1;
  double calc2;
  Scanner in=new Scanner(System.in);
  System.out.println("First number here");
  num1=in.nextInt();
  System.out.println("What do you want to do? add = 1 subtract = 2 divide = 3 multiply = 4");
  calc1=in.nextInt();
  System.out.println("Second number here");
  num2=in.nextInt();
calc2=0; 

if (calc1 == 1)
    calc2=(double)num1+num2;
  if (calc1 == 2)
    calc2=(double)num1-num2;
if (calc1 == 3)
  calc2=(double)num1/num2;
if (calc1 == 4)
  calc2=(double)num1*num2;
System.out.println("Your answer is " +calc2);
   }
}

outcome :

Code:

First number here
1000
What do you want to do? add = 1 subtract = 2 divide = 3 multiply = 4
2
Second number here
500
Your answer is 500.0

question:
the command or however you call it for inputting an int is in.nextInt();
I've tried a few combinations of in.next[whatever]
i just want to know how to input char's so i can make my calc improved

 

The Scanner class doesn't have a method to directly read a char. You should use next() and then charAt(0) to get the first char in the string.

You could always use a DataInputStream instead. Just do:

Code:

		DataInputStream dis = new DataInputStream(System.in);
		dis.readLine();

To read the whole line.
