Palindrome Number descending order using comparator in java

Read Number from Console and Check if it is a Palindrome Number

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

public class InputPalindromeNumberExample

{

public static void main(String[] args)

{

System.out.println("Enter the number to check..");

int number = 0;

try

{      

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

number = Integer.parseInt(br.readLine());

}

catch(NumberFormatException ne)

{

System.out.println("Invalid input: " + ne);

System.exit(0);

}

catch(IOException ioe)

{

System.out.println("I/O Error: " + ioe);

System.exit(0);

}

System.out.println("Number is " + number);

int n = number;

int reversedNumber  = 0;

int temp=0;

while(n > 0)

{

temp = n % 10;

n = n / 10;

reversedNumber = reversedNumber * 10 + temp;

}

if(number == reversedNumber)

System.out.println(number + " is a palindrome number");

else

System.out.println(number + " is not a palindrome number");

   }

}

Simple For loop

public class SimpleForLoopExample

{

public static void main(String[] args)

{

for( ; ; )

for(int index = 0; index < 5 ; index++)

System.out.println("Index is : " + index);

for(int index=0; index < 5 ; index++)

{

System.out.println("Index is : " + index);

index++;

    }

  }

}

Sort Java Vector in descending order using comparator

import java.util.Vector;

import java.util.Collections;

import java.util.Comparator;

public class SortVectorInDescendingOrderExample

{

public static void main(String[] args)

          {

Vector v = new Vector();

v.add("1");

v.add("2");

v.add("3");

v.add("4");

v.add("5");

Comparator comparator = Collections.reverseOrder();

                    System.out.println("Before sorting Vector in descending order : " + v);

Collections.sort(v,comparator);

System.out.println("After sorting Vector in descending order : " + v);

   }

}
