Basic Programming

Print on same line using multiple print statement Append StringBuffer by StringBuffer, String obj Conditional (Ternary) Operator - ? :

Input - Output - Variables

Example of Overriding a Base Class Method Declare, initialize and print String object Example of getting at characters in a String Operator (>>>) Shift Right - with zeros from left Constructor in class to initialize data member Use of Labeled Continue Statement

StringBuffer

Use of some Character Methods Read input from Standard Input Device Declare, initialize, print StringBuffer object Logical OR Operator (|) in If Statement Static Nested Class outside Top-Level Class Declare, initialize, print array of characters Check start and end of a String Operator (<<) Shift Left - with zero from right Example of creating class and using its object Use of Nested Loop

Arrays

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

Standard Libraray Class Methods

Bitwise Operator (&) AND StringBuffer,String obj,Basic Types to strbuf obj Switch Statement for different case labels

Bitwise Operators

Calling Base Class Method from Derived Class Example of arrays of String Example of searching String for character Use of If Statement Example of overloading constructors in a class Use of Break Statement

Classes

Boolean variable on Standard Output Device Show some properties of StringBuffer object Logical or Boolean Negation i.e. NOT (!) Example of Driving and using a Class Declare, initialize, print 2D array of integers Compare Strings by successive corresponding char Operator (>>) Shift Right - sign bit from left Initialization block - initialize data of class Use of the Continue Statement

String

Use of some Math Methods Increment and Decrement Operators Example of creating string obj from char Array Conditional OR Operator (||) in If Statement Example of using Non-Static Nested Class Search element in array using Linear Search Compare strings for equality Bitwise Operator (~) Complement Example creating String obj from StringBuffer obj Use of Do-While Loop

Continue/Break Statement

Example using Abstract Class and Abstract Method Print string on Standard Output Device Example of modifying string objects Conditional AND Operator (&&) in If Statement Example of using user-defined package Copy element of array in another in reverse order Bitwise Operator (|) OR Example extraction of char from StringBuffer obj Use of For Loop

Conditional Statements - Logical Operators

Example of Polymorphism Example of concatination of Strings Example of searching string for subString Use of If-Else Statement Example of using multiple classes Use of Labeled Break Statement

Extending Classes and Inheritance

 
 
 public class JAVA_065
 {

    static int[] values=new int[10];

    int count;

    static
    {
       System.out.println(\"Running static initialization block.\");

       for(int i=0;i<values.length;i++)
          values[i]=(int)(100*Math.random( ));
    }

    {
       System.out.println(\"Running initialization block.\");

       count=10;
    }

    void list_values( )
    {
       for(int i=0;i<values.length;i++)
          System.out.print(values[i]+\" \");

       System.out.println(\"\\nCount = \" + count);

       System.out.println( );
    }


    public static void main(String[] args)
    {
       JAVA_065 obj=new JAVA_065( );

       System.out.println(\"\\nFirst Object : \");

       obj.list_values( );


       obj=new JAVA_065( );

       System.out.println(\"\\nSecond Object : \");

       obj.list_values( );
    }
 }
