Basic Programming


Bitwise Operators

Calling Base Class Method from Derived Class Example of arrays of String Bitwise Operator (&) AND StringBuffer,String obj,Basic Types to strbuf obj Switch Statement for different case labels Use of Break Statement

Classes

Example of searching String for character Use of If Statement Example of overloading constructors in a class 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 Logical or Boolean Negation i.e. NOT (!) 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

Continue/Break Statement

Example using Abstract Class and Abstract Method Compare strings for equality Bitwise Operator (~) Complement Example creating String obj from StringBuffer obj Example of using user-defined package Copy element of array in another in reverse order Print string on Standard Output Device Example of modifying string objects Conditional AND Operator (&&) in If Statement Use of For Loop

Conditional Statements - Logical Operators

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

Extending Classes and Inheritance

Example of searching string for subString Use of If-Else Statement Example of using multiple classes

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 Conditional (Ternary) Operator - ? : 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 Constructor in class to initialize data member 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
 

Program to show the use of While Loop

 
 public class JAVA_028
 {

    public static void main(String[] args)
    {
       int limit=20;
       int sum=0;
       int i=1;

       while(i<=limit)
       {
          sum+=i;
          i++;
       }

       System.out.println(\"Sum of first 20 integers = \" + sum);
    }
 }
