  public static void main(String[] args) { // input Scanner kb=new Scanner(in); // input 2 doubles double num1=kb.nextDouble(); double num2=kb.nextDouble(); // sum out.println(num1+num2); // difference out.println(num1-num2); // product out.println(num1*num2); // quotient out.println(num1/num2); }

  If you use the Scanner class, you would have to import the java.util.Scanner class before your first use. You can use the Scanner class to get input by creating an instance Scanner sc=new Scanner(System.in); which will use the console input for your data. To print (without carriage return), you could use System.out.print("string/message"); To print with carriage return, you could use: System.out.println(""+data +"messages"); Integer data will be converted to Sting and concantenated with any String data. you need to define the integer variables using int k1,k2; and input using the Scanner class, for example: k1=sc.nextInt(); This resumes much of the commands you will need. Use the Java API to help you with syntax, and post your rough copy if you need more help.

  In case you don't have the Java API installed, it can be found at the following link: http://java.sun.com/javase/6/docs/api/
