Computer Programming question (java)?

public static void main(String[] args) {

String s = "Arun";

int i = s.length() - 1;

for (; i >= 0; i--) {

System.out.print(s.charAt(i));

}

}

You could take a string and use a loop to put the characters into an array, then put the characters back into a string backwards using a different loop. I would check Javadocs to see if there isn't already some method that can do this.

You can do it this way in C++ using pointers. I am pretty sure you will easily adapt it to java.. Hope i helped exactly what u want... and i hope i solved your question by writing this program using pointers..

#include <iostream.h>

#include <conio.h>

void main()

{

char ch[100],*p, ct[100], *tp;

p=ch;

cout<<"enter string"<<endl;

*p=cin.get();

while(*p!='$')

{

p++;

*p=cin.get();

}

*p='\0';

p--;

tp=ct;

int i=0;

while(p>=ch)

{

*tp=*p;

p--;

tp++;

}

*tp='\0';

cout<<"Reverse Array"<<endl;

tp=ct;

while(*tp!='\0')

{

cout.put(*tp);

tp++;

}

cout<<endl;

getch();

}

i found some java related questions at http://previouspapers.blogspot.com/2008/03/java-te...

here is your code

import java.util.Scanner;

public class ReverseString{

public static String reverse(String str)

{

String temp="";

for(int i=str.length()-1;i>=0;i--)

temp+=str.charAt(i);

return temp;

}

public static void main(String a[])

{

System.out.print("Enter the string to reverse : ");

Scanner input = new Scanner(System.in);

String s=(String)input.next();

s=reverse(s);

System.out.println("Reversed string :"+s);

}

}

sample output

E:\tli\ya-help>java ReverseString

Enter the string to reverse : hello

Reversed string :olleh
