CC2 FINAL TERM REVIEWER

Character class

Contains standard methods for testing values of characters

Literal string

Sequence of characters enclosed within double quotation marks

class

String is a ______

charAt() method

Indicates position of character that method returns

indexOf() method

Determines whether specific character occurs within String, Returns position of character

setLength() method

Change length of String in StringBuilder object

append() method

Adds characters to end of StringBuilder object

insert() method

Adds characters at specific location within StringBuilder object

setCharAt() method

Changes character at specified position within StringBuilder object

charAt() method

Accepts argument that is offset of character position from beginning of String

Loop

Structure that allows repeated execution of a block of statements

Loop Body

Block of statements, Executed repeatedly

while loop

Executes body of statements continually, As long as Boolean expression that controls entry into loop continues to be true

Definite loop

Performs task a predetermined number of times, Also called a counted loop

Suspect infinite loop

Same output displayed repeatedly, Screen remains idle for extended period of time

Loop control variable

Variable altered and stored with new value

Empty body

Body with no statements, Caused by misplaced semicolons

for Loop

Used when definite number of loop iterations is required

do.. while Loop

a posttest loop, The loop body executes before the loop-controlling questions is asked even one-time.

inner loop

must be entirely contained within the outer loop; loops can never overlap.

WHILE LOOP

CONTROLLING BOOLEAN EXPRESSION IS THE FIRST STATEMENT

FOR

A CONCISE FORMAT IN WHICH TO EXECUTE LOOPS

DO...WHILE LOOP

CONTROLLING BOOLEAN EXPRESSION IS THE LAST STATEMENT

Array

is a collection of Homogenous, Ordered and Finite set of elements

Homogenous

implies all elements must be of the same type and have the same structure.

Adding

inserts new element in a position specified by the index, also sometimes referred to as Assigning.

Retrieving

It is also called Accessing, To retrieve an element we must know the Index value

Deleting

In this way the element to be deleted is overwritten by the element to its right.

Inserting

It adds new element in a specified position, without replacing any existing element

Array Traversing

Traversing involves accessing and processing an array element exactly once, also called Visiting.

ragged array

Each row in a two-dimensional array is itself an array. So, the rows can have different lengths. Such an array is known

class

is a blueprint or template used to create objects. It represents the properties (attributes/fields) and behaviors (methods) that objects of that class will have.

Class header

Optional access modifier, Any legal identifier for the name of class

public class

Accessible by all objects

static class variables

Are not instance variables

attributes

are also known as fields or member variables within a class. They represent the data or state associated with objects created from that class.

Access modifiers

Place entire method within class that will use it

static variable

also known as a class variable, is a variable that belongs to the class itself rather than to any instance (object) of the class.

Local variable

Known only within boundaries of method, Each time method execute

Methods

are functions that are defined inside a class that describe the behaviors of an object.

constructor method

is a special type of method used to initialize objects. It is called when an object of a class is created using the new keyword.

default constructor

A constructor with no parameters

void method

A method without a return value in Java, perform a task or an action but do not return any value upon completion.

object

is a fundamental building block of a class.
