ConvertCharToString.java 

package com.mkyong.utils;

public class ConvertCharToString {

    public static void main(String[]args) {

        String website = "/";

       //convert a String into char
        char charH = website.charAt(0);//h
        char charP = website.charAt(3);//p
        char charM = website.charAt(11);//m
        System.out.println(charH);
        System.out.println(charP);
        System.out.println(charM);

       //convert char back to String
        String temp = Character.toString(charM);

        if ("m".equals(temp)) {
            System.out.println("match");
        }

    }

}
