Question

Declare k, d, and s so that they can store an integer , a real number, and a small word (under 10 characters ).

Use these variables to first read in an integer , a real number, and a small word and print them out in reverse order (i.e., the word, the real, and then the integer ) all on the same line, separated by EXACTLY one space from each other.

Then, on a second line, print them out in the original order (the integer , the real, and the word), separated again by EXACTLY one space from each other.

Explanation / Answer

import java.util.*;
import java.util.Scanner;

class Reverse
{
public static void main(String args[])
{
String s,k, reverse = "";
int no,k,rev=0,n, reverse_number = 0;
Scanner in = new Scanner(System.in);

System.out.println("Enter a string to reverse");
k = in.nextLine();
System.out.println("Enter the number to reverse");
n = in.nextInt();
System.out.print("Enter real Number you want to reverse : ");
s=in.readLine();
int length = k.length();

for ( int i = length - 1 ; i >= 0 ; i-- )
reverse = reverse + k.charAt(i);

while( n != 0 )
{
reverse_number = reverse_number * 10;
reverse_number = reverse_number + n%10;
n = n/10;
}

no=Integer.parseInt(s);

while(no > 0)
{
k = no % 10;
rev = rev * 10 + k;
no=no/10;
}

System.out.println("Reverse Number is : "+rev);
  
System.out.println("Reverse of entered number is "+reverse_number);

System.out.println("Reverse of entered string is: "+reverse);
}
}
