what are objects in java?

objects have the following
-attributes/ data
-behaviors/ operation

anytime a division is done you get a quotient and remainder in java.

Addition gives you an int back
subtraction gives you a int back
multiplication gives you a in back

% —Modulus
/ —Division

What are real numbers?
any rational or irrational number

integer division vs floating point division
late night talk do the operators have two different set of sequence for solving the same problem?
why yes they do completely different.

// example for 9-5-12

public class Example1
{
  public static void main ( String [] args )
  {
    
    double a = 5.2665;
    double b = 2.3232;
    double result;
    
    result = a + b;
    System.out.printf("%.2f + %.2f = %.2f\n", a, b, result);
    
    result = a - b;
    System.out.printf("%.2f - %.2f = %.2f\n", a, b, result);
   
    result = a * b;
    System.out.printf("%.2f * %.2f = %.2f\n", a, b, result);
   
    result = a / b;
    System.out.printf("%.2f / %.2f = %.2f\n", a, b, result);
    
    result = a % b;
    System.out.printf("%.2f %% %.2f = %.2f\n", a, b, result);
