Conditional Statements - Logical Operators

Example of Polymorphism Example of concatination of Strings Bitwise Operator (|) OR Example extraction of char from StringBuffer obj Example of using multiple classes Use of Labeled Break Statement

Extending Classes and Inheritance

Example of searching string for subString Use of If-Else Statement Conditional (Ternary) Operator - ? :

Input - Output - Variables

Example of Overriding a Base Class Method Declare, initialize and print String object Print on same line using multiple print statement Append StringBuffer by StringBuffer, String obj Constructor in class to initialize data member Use of Labeled Continue Statement

StringBuffer

Use of some Character Methods Example of getting at characters in a String Operator (>>>) Shift Right - with zeros from left Static Nested Class outside Top-Level Class Declare, initialize, print array of characters Read input from Standard Input Device Declare, initialize, print StringBuffer object Logical OR Operator (|) in If Statement Use of Nested Loop

Arrays

Example of Copying i.e. Clonning Objects Check start and end of a String Operator (<<) Shift Left - with zero from right Example of creating class and using its object Example of using a Static Nested Class Sort content of an array using Bubble Sort Integer variable on Standard Output Device Example of creating char Array from String obj Logical AND Operator (&) in If Statement Use of While Loop Use of Switch Statement Example of Multiple Levels of Inheritance Use of Comparison operator (==) for String Bitwise Operator (^) XOR (Exclusive OR) Change char in StringBuffer obj- reverse content Example of using a recursive method in class Declare, initialize, print an array of integers

Standard Libraray Class Methods

Example of extracting subString from a String Use of Nested If-Else Statements Switch Statement for different case labels

Bitwise Operators

Classes

Example of searching String for character Use of If Statement Logical or Boolean Negation i.e. NOT (!) Example of Driving and using a Class Declare, initialize, print 2D array of integers Boolean variable on Standard Output Device Show some properties of StringBuffer object Use of the Continue Statement

String

Use of some Math Methods Compare Strings by successive corresponding char Operator (>>) Shift Right - sign bit from left Initialization block - initialize data of class Example of using Non-Static Nested Class Search element in array using Linear Search Increment and Decrement Operators Example of creating string obj from char Array Conditional OR Operator (||) in If Statement Use of Do-While Loop
