Problem #18

/*
 * 18. Write a Java class called Reverse, which defines a main() method that asks the user to enter a String s, 
 * and displays a new String consisting of the characters in s in the reverse order. 
 * You MUST NOT use any methods defined in the String class other than charAt() and length()
 */

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Reverse {

    public static void main(String[] args) {
        BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
        
        String s = new String();
        
        System.out.println("Please enter a string: ");
        
        try {
            s = input.readLine();
        } catch (IOException ex) {
            System.err.println(ex);
        }

        char [] chr_array = new char[s.length()];
        
        int j = 0;
        
        for (int i = s.length()-1; i >= 0;i--) {
            chr_array[j] = s.charAt(i);
            j++;
        }
        
        //new string in reverse order
        String rs = new String(chr_array);
        
        System.out.println("The reverse is > "+rs);
    }

}

master nakoi pangutana dba sa instruction kai
You MUST NOT use any methods defined in the String class other than charAt() and length()
dyn sa code kai
char [] chr_array = new char[s.length()];
lahi ra na sila?

[doomsweek]

String.length() raman ang function diha.

Kalimot nako sa java pero i think sa kani na line:

char [] chr_array = new char[s.length()];

kay ga declare na siya ug char type array named chr_array with size s.length()

ok ra na bro kay array man na siya. Wala man gibutang nga do not use array. Ang method diha kay length()
