Write code to Capitalizes the first letter of the given string.

Demo

//package com.book2s;

public class Main {
    public static void main(String[] argv) {
        String text = "book2s.com";
        System.out.println(capitalize(text));
    }// w ww.ja  va 2 s .c om

    /**
     * Capitalizes the first letter of the given string.
     * 
     * @param text the string to capitalize.
     * 
     * @return the modified string.
     */
    public static String capitalize(String text) {
        String h = text.substring(0, 1).toUpperCase();
        String t = text.substring(1);
        return h + t;
    }
}
