Let us suppose that a number is 12345 and we want to reverse this number like 54321 so here is a java program which reverse your any number given by you.

**public class reverseNumber**

{

public static void
main(String as[])

{

System.out.println("Please Enter your Number want to reverse

int
n=Integer.parseInt(as[0]);

int m=0;

int r=0;

while(n!=0)

{

r=n%10;

m=m*10+r;

n=n/10;

}

System.out.println("Reverse
number:----"+m);

}

}
