Write a program that will allow a user to input his name. The prompt and input >Update:

here's what i got so far:

import java.io.*;

import java.util.*;

public class NameReversal{

public static void main(String [] args){

Scanner kbReader=new Scanner(System.in);

System.out.print("Please enter your name._");

String s=kbReader.nextLine();

int len=s.length();

...i just have no clue what to do with the for loop....

You can also solve the problem this way.

import java.util.Scanner;

public class NameReversal {

public static void main(String[] args) {

Scanner kbReader = new Scanner(System.in);

System.out.print("Please enter your name._");

String s = kbReader.nextLine();

int len = s.length();

String reversedString = "";

for(int i = 0; i < len; i++) {

int j = len - i - 1;

reversedString += s.substring(j, j+1).toLowerCase();

}

System.out.println(reversedString);

}

}

I prefer this solution because the for loop clear goes from 0 to the length of the input.

I use a trick to calculate out the reverse string by making the index go backwards. It's possible to combine this logic into the for loop, but that's more confusing for me.

Yeah, do you have some sample code? You should at least try, it's nothing too hard, and i'll help out.

Try implementing this:

First, add a String reverseName="";

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

reverseName+=s.charAt(i);

}

EDITED: look at the for loop again.

After the loop (outside of it), add:

reverseName = reverseName.toLowerCase();

And print reverseName to output. That should be all.

Let me know if you have problems.

since the main class is tester,you cant able to create object for circle and use it, Try this code: class Circle { Circle(double d) { System.out.println(d*2); } } public class Tester extends Circle { Tester(double d) { super(d); } public static void main( String args[]) { Circle cirl = new Circle (35.5); } } or class Circle { void diameter(double d) { System.out.println(d*2); } } public class Tester extends Circle { public static void main( String args[]) { Circle cirl = new Circle (); cirl.diameter(35.5); } }

One curly brace should be right and the other outside left. You have them both facing the same direction, for both sets.
