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....Show more

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();
}

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);
}
}
