1. Trace the evaluation of the following expressions, and give their resulting values (remember
order of precedence rules and concatenation):

1. 2 + 2 + 3 + 4
2. “2 + 2” + 3 +
3. 2 + “2 + 3” +
4. “hello 34 “ +
5. “1” + 2 + 3 +

4
4
2 * 4
“4” + 5 * 6 + “7” + (8 + 9)

1. Imagine you are writing a personal fitness program that stores the user’s age, gender, height (in
   feet or meters) and weight (to the nearest pound or kilogram). Declare variables with the
   appropriate names and types to hold this information.
2. Imagine you are writing a program that stores a student’s year (Freshman, Sophomore, etc.), the
   number of courses the student is taking, and his or her GPA on a 4.0 scale. Declare variables
   with the appropriate names and types to hold this information.
3. Which of the following is the correct syntax for declaring a real number variable named grade
   and initializing its value to 4.0?
   a. int grade : 4.0;
   b. grade = double 4.0;
   c. double grade = 4.0;
   d. grade = 4;
   e. 4.0 = grade;
4. Write the complete Java code for the Pastoral College student program: the program should
   include a student’s name, major field of study and GPA. The program should also display a
   student’s data with the message “Dean’s list” if the student’s GPA is above 3.5; display
   “Academic probation” if the GPA is below 2.0; and no message if the GPA is between 2.0 and 3.5
   inclusive.
