Week 3

1. For each expression in the left-hand column, indicate its value in the right-hand column. List a constant of appropriate type (e.g., 7.0 for a double, true or false for a boolean, Strings in "" quotes).

Expression	Value
4.5 / 3 / 2 + 1
57 % 10 / 3 + 1.25 * 4
5 * 6 / 4 % 3 - 23 / (14 % 6)
8 - 4 + "17" + 7.5 * 2
46 / 3 / 2.0 / 3 * 4/5

2. Given the following program

public class MysteryWho {
    public static void main(String[] args) {
        String whom = "her";
        String who = "him";
        String it = "who";
        String he = "it";
        String she = "whom";

        sentence(he, she, it);
        sentence(she, he, who);
        sentence(who, she, who);
        sentence(it, "stu", "boo");
        sentence(it, whom, who);
    }

    public static void sentence(String she, String who, String whom) {
        System.out.println(who + " and " + whom + " like " + she);
    }
}

Write the output of each of the following calls.

sentence(he, she, it);	
sentence(she, he, who);	
sentence(who, she, who);	
sentence(it, "stu", "boo");	
sentence(it, whom, who);

3. Consider the following method.

public static void ifElseMystery1(int x, int y) {
    int z = 4;
    if (z <= x) { 
        z = x + 1; 
    } else { 
        z = z + 9; 
    } 
    if (z <= y) { 
        y++; 
    } 
    System.out.println(z + " " + y); 
}

For each call below, indicate what output is produced.

ifElseMystery1(3, 20);	
ifElseMystery1(4, 5);	
ifElseMystery1(5, 5);	
ifElseMystery1(6, 10);
