Declaration of an Array as a String - correct answer String [] name = new String[12]; In Java, What is the first value of any array - correct answer 0 Declaration of an Array as a Double - correct answer double [] numbers = new double[2]; Declaration of an Array as a Integer - correct answer int [] x = new int[3]; What does the number declare when initializing a new array value? - correct answer The number of spaces there will be in the array If you were to have 4 spaces in an array how you you add value to each space - correct answer String [] name = new String[4]; String[0] = "TJ Roe"; String[1] = "Patrick Lee"; String[2] = "Jarod Funk"; String[3] = "Jesus Christ the homeboy"; Integer.MAX_VALUE; - correct answer 2^31 - 1 Integer.MIN_VALUE; - correct answer -2^31; Matrix - correct answer A rectangular array of numbers or other mathematical objects, for which operations such as addition and multiplication are defined. printf(); - correct answer Method that solves for formatting problems in code. Use is Recommended or typical print() and println() Format Specifier imbedded within String literal - correct answer 1. The leading percent sign (%) 2. Optional flag or specifier 3. A converter (s, d, or f) *s = lowercase string* *S = UPPERCASE STRING* *d = double* *f = float* For-Each Loop - correct answer for(String person : names) { Sln(person); } For Loop - correct answer for (int index = 0; index <= 9; i++) { Sln(names[index]); } Writing Arithmetic Statments - correct answer When Writing Arithmetic Statements you can't declare variables like you typically would in math. Remember if you are reusing a variable and changing the value of it do x = x + 1 Ex. int x = 1; x = x + 1; In Latence Terms: x = 1 + 1 Sln(x); OUTPUT: x = 2; Generating Random Numbers - correct answer import .Random; Random rand = new Random(); int x = Int(12); (Creates a random integer between 0 and 12) OR Mm(); (Creates a random double between 0.0 and 1.0) Writing Text Files - correct answer import .File; import .IOException; import .PrintWriter; public static void main(String[] args) throws IOException { PrintWriter output = new PrintWriter(newFile("")); ln("Hello World"); (); Reading Text Files - correct answer import .File; import .IOException; import .Scanner; public static void main(String[] args) throws IOException { File names = new File("/Users/timothyroejr/Desktop/Comp Science/QuizletStuff/src/"); Scanner inFile = new Scanner(names); String [] people = new String[3]; int index = 0; for (int i = 0; i < index; i++) { people[index] = inFLine(); index++ } for (Str
