ObjectAn instance of a class. A software model of something that exists in the real world or in the imagination. They have attributes or characteristics (things they "know") and behaviors (things they can do). ClassThe basic unit of Java Programming; describes a set of objects with the same behavior. A programmer-defined abstract data type (ADT). An ADT is a domain of objects and a set of operations on those objects. MethodsA sequence of instructions that implements one of the behav...

What will be printed by the statement below? S("O"myt"no!"); Select one: a. O myt no! b. O"myt"no! c. O"myt"no! d. O"my "no!D What (if any) type of error occurs with the following code if the user input is ABC? public static void main(String[] args) { Scanner in = new Scanner(S); S("Enter a number: ");

A program is a sequence of instructions and decisions that the computer carries out. statement best describes a computer program? Machine Code What term is used to refer to the computer instructions that are executed by a CPU? high-level What term is used to refer to languages that allow programmers to describe tasks at a higher conceptual level than machine code? Compiler What tool translates high-level instructions into low level machine code? uppercase letter By convention among Jav...

VARIABLE PART 1 VARIABLE PART 1 a variable is a named item, such as x or numPeople, used to hold a value. An assignment assigns a variable with a value, such as x = 5. That assignment means x is assigned with 5, and x keeps that value during subsequent assignments, until x is assigned again. Increasing a variable's value by 1, as in x = x + 1, is common, and known as incrementing the variable. A variable declaration is a statement that declares a new variable, specifying the variable...
