1. For each expression in the left-hand column, indicate its value in the right-hand column. Be sure to list a constant of appropriate type (e.g., 7.0 rather than 7 for a double, Strings in quotes).

Expression	Value
8 * 2 - 2 * 3	________________
87 % 10 + 28 % 5 % 2	________________
1 + 2 + "3" + 4 + 5 * 6	________________
2 * 2.3 + 5 / 2 + 19 / 4 * 2.0	________________
436 / 10 / 5 - 9 / 2 * 2.5 / 2	________________

2. In your own works explain the difference between print() and println().

3. What are the values of first and second at the end of the following code?

int first = 8;
int second = 19;
first = first + second;
second = first - second;
first = first - second;

4. What is the output of the following sequence of loops?

for(int i = 1; i <= 5; i++){
  for(int j = 1; j <= 10; j++){
    System.out.print((i * j) + " ");
  }
  System.out.println();
}

5. Consider the following program. what is the output produced by this program.

    public class Mystery {
        public static void main(String[] args) {
            String hear = "bad";
            String song = "good";
            String good = "hear";
            String walk = "talk";
            String talk = "feel";
            String feel = "walk";
   
            claim(feel, song, feel);
            claim(good, hear, song);
            claim(talk, "song", feel);
            claim(talk, "bad", walk);
        }
   
        public static void claim(String hear, String good, String song) {
            System.out.println("to " + hear + " the " + song + " is " + good);
        }
    }
