Assignment 1, Question 4


1. Line: 3
   Error: Class name Kumbers does not match the file name Numbers.java
   Type: Syntactic
   Fix: Change class name from Kumbers to Numbers
   New line: public class Numbers
   
2. Line: 8
   Error: The semicolon (;) right after difference makes product; an invalid
          variable declaration
   Type: Syntactic
   Fix: Replace the semicolon right after difference with a comma (,)
   New line: int sum, difference, product;
   
3. Line: 16
   Error: There should be a semicolon to mark the end of the statement
   Type: Syntactic
   Fix: Add a semicolon at the end of the line
   New line: secondNumber = input.nextInt();
   
4. Line: 20
   Error: The purpose of the line is to compute the difference of the two
          numbers, but their sum is computed instead
   Type: Semantic
   Fix: Replace the plus sign (+) by a minus sign (-)
   New line: difference = firstNumber - secondNumber;
   
5. Line: 22
   Error: The division of two values of type int results in a value of type int,
          so the decimal part is lost
   Type: Semantic
   Fix: Cast one of the two operands to float by writing (float) in front of it,
        thus forcing floating point division
   New line: division = (float)firstNumber / secondNumber;

6. Line: 26
   Error: The String literal "The difference is: " and the value of variable
          difference are not properly combined
   Type: Syntactic
   Fix: Add a plus sign between "The difference is: " and difference
   New line: System.out.println("The difference is: " + difference);
