StringBuffer:
=============
reverse():
==========
==> can use to reverse the content of the stringbuffer.
Syntax:
	sbo.reverse()

class StringBufferReverse{
    public static void main(String[] args)
    {
        StringBuffer sb = new StringBuffer("Java");
        
        System.out.println("The Given Stringbuffer = "+sb);
        
        sb.reverse();
        
        System.out.println("The Stringbuffer after the reverse = "+sb);
    }
}

=================================================

toString()
==========
==> can use to convert the stringbuffer to the string.
Syntax:
	String object = sbo.toString()


Q: WAP TO CHECK WHETHER THE GIVEN STRING IS PALINDROME OR NOT USING STRINGBUFFER.
==================================================================================

class PalindromeCheck{
  public static void main(String[] args)
  {
    StringBuffer sb1 = new StringBuffer("level");
    String s1 = sb1.toString();
    
    String s2 = (sb1.reverse()).toString();
    
    if(s1.equals(s2))
    {
      System.out.println("Strings are Palindrome.");
    }
    else
    {
      System.out.println("Strings are not Palindrome.");
    }
  }
}

StringBuffer Comparison:
========================

class EqualityCheck{
  public static void main(String[] args)
  {
    StringBuffer s1 = new StringBuffer("Java");
    StringBuffer s2 = new StringBuffer("Java");
    
    if(s1 == s2)
    {
      System.out.println("Equal.");
    }
    else
    {
      System.out.println("Not Equal.");
    }
  }
}

===========================================
class EqualityCheck{
  public static void main(String[] args)
  {
    StringBuffer s1 = new StringBuffer("Java");
    StringBuffer s2 = new StringBuffer("Java");
    
    String s3 = new String("Python");
    String s4 = new String("Python");
    
    if(s1.equals(s2))
    {
      System.out.println("Equal.");
    }
    else
    {
      System.out.println("Not Equal.");
    }
    
    if(s3.equals(s4))
    {
      System.out.println("Equal.");
    }
    else
    {
      System.out.println("Not Equal.");
    }
  }
}
========================================
delete():
========
Syntax:
	sbo.delete(start,end)


class DeleteData{
  public static void main(String[] args)
  {
    StringBuffer sb = new StringBuffer("Java Fullstack");
    
    System.out.println(sb);
    
    sb.delete(5,9);
    
    System.out.println(sb);
  }
}

==========================================================
StringBuilder:
==============
java.lang.StringBuilder;

class StringBuilderDefinion{
  public static void main(String[] args)
  {
    StringBuilder sbo = new StringBuilder("Java");
    // StringBuilder s = "Java";
    
    System.out.println(sbo);
  }
