AP Computer Science A

Definition

The "public static" keywords are used in Java to declare that a method or variable can be accessed and used without creating an instance of the class. "Public" means it is accessible from anywhere, and "static" means it belongs to the class itself rather than any specific instance.

Consider the following method: public static int powerOfTwo(int n) { if (n == 0) { return 1; } else { return 2 * powerOfTwo(n - 1); } } Assume that the following code segment appears in a class: int result = powerOfTwo(3); System.out.println("2 raised to the power of 3: " + result); What is printed as a result of executing the code segment?
Consider the following method: public static boolean isEven(int number) { return number % 2 == 0; } Assume that the following code segment appears in a class: boolean result = isEven(7); System.out.println("Is 7 an even number? " + result); What is printed as a result of executing the code segment?
Consider the following method: public static String capitalize(String word) { return word.substring(0, 1).toUpperCase() + word.substring(1); } Assume that the following code segment appears in a class: String result = capitalize("hello"); System.out.println("Capitalized word: " + result); What is printed as a result of executing the code segment?
What does the following code do? public static int codeBlock(int[] array) { int x = 1; for (int y: array) { x *= y; } return x; }
What does the following code do? public static boolean codeBlock(int[] array) { for (int i = 0; i < array.length - 1; i++) { for (int j = i + 1; j < array.length; j++) { if (array[j] == array[i]) { return true; } } } return false; }
What does the following code do? public static int[] codeBlock(int[] array) { int firstItem = array[0] for (int i = 0; i < array.length - 1; i++) { array[i] = array[i+1]; } array[array.length - 1] = firstItem; return array; }
What does the following code do? public static int[] codeBlock(ArrayList<Integer> arrayList) { int[] newArray = new int[arrayList.size()]; for (int i = 0; i < arrayList.size(); i++) { newArray[i] = arrayList.get(i); } return newArray; }
What does the following code do? public static boolean codeBlock(int[] array) { for (int i: array) { if (i >= 25) { return false; } } return true; }
What does the following code do? public static boolean codeBlock(ArrayList<Integer> array) { for (int i: array) { if (i % 3 == 1 || i % 3 == 2) { return false; } } return true; }
