Write a program in java to find the length of given String.

Here is the three way to find the length of given string.these are given following.

Method #1

class StringLength

{

          public static void main(String[] args)

          {

                   String str="hi this is String";

                   int count=0;

                   for(char c:str.toCharArray())

                   count++;

   System.out.println("Length of string by userdefined method ::"+count);

          }

}                

Output:

Method #2

class StringLength

{

       public static void main(String[] args)

       {

              String str="hi this is String";

              System.out.println("Length of string library function ::"+str.length());

       }

}                

Output:

Method #3

class StringLength

{

       public static void main(String[] args)

       {

              String str="hi this is String";

              int i=0,cc=0;

              try{

                    for(i=0,cc=0;0<=i;i++,cc++)

                    str.charAt(i);

                   }

             catch(Exception e){

                    System.out.println("Length of string by exception:: "+cc);

                     }

       }

}                

Output:
