BJP5 Self-Check 5.1: whileLoops

Language/Type: Java basics while loops
Author: Will Beebe (on 2019/09/19)

For each of the following while loops, how many times will the loop execute its body? Remember that "zero," "infinity," and "unknown" are legal answers.

1. 
int x = 1;
while (x < 100) {
    System.out.print(x + " ");
    x += 10;
}
2. 
int max = 10;
while (max < 10) {
    System.out.println("count down: " + max);
    max--;
}
3. 
int x = 250;
while (x % 3 != 0) {
    System.out.println(x);
}
4. 
int x = 2;
while (x < 200) {
    System.out.print(x + " ");
     x *= x;
}
5. 
String word = "a";
while (word.length() < 10) {
    word = "b" + word + "b";
}
System.out.println(word);
6. 
int x = 100;
while (x > 0) {
    System.out.println(x / 10);
    x = x / 2;
}
