Concepts of Programming Languages

Please provide the full answers to question 2 & 3 (below)!

2. How many lexemes does the following Java code contain?

1. public class RepeatString {

2. public static void main(String args[]) {

3. Scanner input = new Scanner(System.in);

4. System.out.println("Enter a string: ");

5. String phrase = input.nextLine();

6. System.out.println("Enter # times to repeat string: ");

7. int repetitions = input.nextInt();

8. repeat(phrase, repetitions);

9. }

10. public static void repeat(String str, int reps) {

11. for (int i = 1; i

12. System.out.println(i + ". Repeat:\t" + str);

13. }

14. } }

Give the number of lexemes on each line (using the line numbers shown) as well as the

total number of lexemes.

3. Problem 17 in Chapter 1 of Sebesta:

Some programming languages --- for example, Pascal --- have used the semicolon to

separate statements, while Java uses it to terminate statements. Which of these, in your

opinion, is most natural and least likely to result in syntax errors? Support your answers.
