title: input 2 variables(user input by "Buffered Reader") to be pass to a class?
body: <p>i am a beginner at java language and i use "text pad". i have a problem with my simple program. my task is to input 2 values and show the "sum","difference","product" and "quotient" altogether. (simple right?) in which , here below is the class that supposed to be doing the job of arithmetic. in which is "correct" as i compiled.</p>
  
  <pre><code>public class mathclass
  {
  
      int x;
      int y;
      int total;
  
  
      void add ()
      {
          total = x+y;
      }
  
      void sub ()
      {
          total = x-y;
      }
  
      void multi ()
      {
          total = x*y;
      }
  
      void div ()
      {
          total = x/y;
      }
  
  }
  </code></pre>
  
  <p>And here is the main program that supposed to be the input and output of the program.
  my problem here is that i can't pass the 2 variables (num1 and num2) to "mathclass"
  i did research on how to pass 2 variables to a another class. but there is nothing same to mine that i have. i did use some like the putting "private or public" on the variables.
   my teacher said to use the BufferedReader for input. and i am having a hard time how to get this program right. (sorry if i had wrong english(if i am wrong. ))</p>
  
  <pre><code>import java.io.*;
  public class mathmain
  {
  
      static BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
  
      public static void main(String[]args)throws IOException
      {
  
  
          mathclass math1 = new mathclass();
  
          System.out.print("Enter 1st Number :");
          num1 = Integer.parseInt(br.readLine());
          System.out.println(" ");
  
          System.out.print("Enter 2nd Number :");
          num2 = Integer.parseInt(br.readLine());
          System.out.println(" ");
  
          System.out.println(" ");
          System.out.println(" ");
          System.out.println(" ");
  
          math1.add();
          {
              System.out.print("Sum : ");
              System.out.println(math1.total);
          }
          System.out.println(" ");
          math1.sub();
          {
              System.out.print("Difference : ");
              System.out.println(math1.total);
          }
          System.out.println(" ");
  
          math1.multi();
          {
              System.out.print("Product : ");
              System.out.println(math1.total);
          }
          System.out.println(" ");
          math1.div();
          {
              System.out.print("Quotient : ");
              System.out.println(math1.total);
          }
      }
  }
