String Methods:
===============

Getting of the Unicode Value of the Character in the given string:
==================================================================
Alphabets
	A-Z ==> 65 to 90
	a-z ==> 97 to 122
	0-9 ==> 48 to 57
	special characters etc.

codePointAt():
=============
Syntax:
	string-object.codePointAt(index)

class GettingUnicodeValues{
    public static void main(String[] args)
    {
        String s1 = new String("Hello");
        
        System.out.println("The Unicode values of each character = ");
        System.out.println(s1.codePointAt(0));
        System.out.println(s1.codePointAt(1));
        System.out.println(s1.codePointAt(2));
        System.out.println(s1.codePointAt(3));
        System.out.println(s1.codePointAt(4));
        // System.out.println(s1.codePointAt(5));
    }
}

Q: WAP TO PRINT ALL THE UNICODE VALUES OF THE STRING CHARACTERS USING LOOP.

/*
The Unicode of character = 65
*/

import java.util.Scanner;

class GettingUnicodeValues{
    public static void main(String[] args)
    {
        Scanner sco = new Scanner(System.in);
        
        System.out.println("Enter the string:");
        String s = sco.nextLine();
        
        System.out.println("The Unicode Values = ");
        for(int i = 0;i < s.length();++i)
        {
            System.out.println(s.charAt(i)+" = "+s.codePointAt(i));
        }
    }
}
==================================
next() Vs nextLine():
====================
next() ==> can read the string characters up to the space
nextLine() ==> can read all the characters of the string including the space also.

============================================
codePointCount():
===============
Syntax:
	getting of the number of  Unicode values from the range:
		String-object.codePointCount(start-index, end-index);


class GettingUnicodeValues{
    public static void main(String[] args)
    {
        String s2 = "Hello Java";
        
        System.out.println(s2.codePointCount(4,7));
        System.out.println(s2.codePointCount(1,9));
        // System.out.println(s2.codePointCount(0,20));
        // System.out.println(s2.codePointAt(20));
    }
}

=======================================
// WAP TO ACCEPT THE STRING AND PRINT THE UNICODE VALUES OF THE CHARACTERS FROM INDEX 1 TO 5. 

import java.util.Scanner;
class GettingUniCodeValues{
    public static void main(String[] args)
    {
        Scanner s = new Scanner(System.in);
        
        System.out.println("Enter a string:");
        String s1 = s.nextLine();
        
        System.out.println("The Unicode values from the given range are = ");
        for(int i = 1;i <= 5;++i)
        {
            System.out.println(s1.charAt(i)+" = " +s1.codePointAt(i));
        }
    }
}
=================================
codePointBefore():
=================
can accept an index value
return a Unicode values of the previous character to the specified index.
Syntax:
	str-obj.codePointBefore(Index)

class Unicode{
    public static void main(String[] args)
    {
        String s = "Hello World!";
        
        System.out.println(s.codePointBefore(5));
    }
}
====================================
contains():
==========
==> used to check about the membership of the specified character.
Syntax:
	str.contains("character")

class MembershipCheck{
    public static void main(String x[])
    {
        String s = "Hello";
        
        System.out.println(s.contains("l"));
        System.out.println(s.contains("llO"));
    }
}

===========================================

// WAP TO COUNT THE NUMBER OF CHARACTERS OF THE STRING WITHOUT length() method.

import java.util.Scanner;

class StringLnegth{
    public static void main(String[] args)
    {
        Scanner sco = new Scanner(System.in);
        System.out.println("Enter the string:");
        String s = sco.nextLine();
        // Converting the string to the character array
        char[] ar = s.toCharArray();
        
        int count = 0;
        for(char a : ar)
        {
            count++;
        }
        System.out.println("The Total Number of caharacters of the string = "+count);
    }
}

========================================
Assignment:
===========
1) WAP TO REVERSE THE STRING.
2) WAP TO COUNT NUMBER OF VOWELS, CONSONANTS AND DIGITS OF THE STRING.
"HELLO123"
VOWELS = 2
CONSONANTS = 3
DIGITS = 3
