Learning debugging is important if you like to be a programmer. To verify a program is doing what it should, a programmer should know the expected (correct) values of certain variables at specific places of the program. Therefore make sure you know how to perform the instructions by hand to obtain these values. Remember, you should master the technique(s) of debugging. Create a new project Assignment02 in NetBeans and copy the following program into a new Java class. The author of the program intends to find the sum of the numbers 4, 7 and 10. public class Assignment02Q1a { public static void main(String[] args) { int from = 4; } int to = 10; int sum= 0; for (int i-from; i<to; i++) { sum += i; } System.out.println("The sum is "+sum); (i) Run the program. What is the output? (ii) What is the expected value of sum just before the for loop is executed? // (1) // (2) (iii) Write down the three expected intermediate sums after the integers 4, 7 and 10 are added one by one (in the given order) to an initial value of zero. (iv) Since we have only a few executable statements here, the debugging is not difficult. Insert a System.out.println() statement just after the statement indicated by the comment "// (2)" to print out sum. What are the values of sum printed (press Ctrl-C to stop the program if necessary)? (v) What modification(s) is/are needed to make the program correct? NetBeans allows you to view values of variables at specific points (called break points). This saves you the efforts of inserting/removing println() statements. Again, you must know the expected (correct) values of those variables at the break points. If you like, you can try to explore the use break points yourself.
