Consider the following code segment. int num1 = 0; int num2 = 3; while ((num2 != 0) && ((num1 / num2) >= 0)) {   num1 = num1 + 2;   num2 = num2 – 1; } What are the values of numl and num2 after the while loop completes its execution?

Consider the following method. public int mystery(int num) { int x = num; while (x > 0) { if (x / 10 % 2 == 0) return x; x = x / 10; } return x; } What value is returned as a result of the call mystery(1034) ?

Consider the following code segment. int k = 1; while (k < 20) {   if ((k % 3) == 1)     System.out.print(k + " ");     k++; }   What is printed as a result of executing this code segment?

Consider the following two code segments. Code segment II is a revision of code segment I in which the loop header has been changed. I. for (int k = 1; k = 1; k–) { System.out.print(k); } Which of the following best explains how the output changes from code segment I to code segment II?

Consider the following method. public String wordPlay(String word) { String str = “”; for (int k = 0; k < word.length(); k++) { if (k % 3 == 0) { str = word.substring(k, k + 1) + str; } } return str; } The following code segment appears in another method in the same class as wordPlay. System.out.println(wordPlay("Computer Science")); What is printed as a result of executing the code segment?

Consider the following method. public static String changeStr(String str) { String result = “”; for (int i = str.length() – 1; i >= str.length() / 2; i -= 2) { result += str.substring(i, i + 1); } return result; } What value is returned as a result of the method call changeStr(“12345”) ?

Consider the following code segment. int j = 1; while (j < 5) { int k = 1; while (k < 5) { System.out.println(k); k++; } j++; } Which of the following best explains the effect, if any, of changing the first line of code to int j = 0; ?
