Length Of The String Without Using Java Built In Length Method :

Java Code With Example

The length of the string is easy to define , it is the number of characters in the string including white spaces .
Java make the things easy as it provides the built in length method for the String class (java.lang.String) which is a final class .
for example :
String demo = ” This is a Java built-in method example “
int length= demo.length();

To use the Java built-in method to calculate the length of the string .
Then there is also a way to calculate the length of the string

You can count characters in two ways.

Including space
Excluding space

Below there are 2 programs to count characters in a string, I hope this might help you.

1.Program to count characters in a string including space

import java.util.Scanner;
public class Program
{
public static void main(String[] args)
{
System.out.println(“Enter the String”);
Scanner scan=new Scanner(System.in);
String input = scan.nextLine();
char [] ch = input.toCharArray(); // converts string into character array
System.out.println(ch.length); // prints the character count including space
}
}

2.Program to count characters in a string Excluding space

import java.util.Scanner;
public class Program
{
public static void main(String[] args)
{
System.out.println(“Enter the String”);
Scanner scan=new Scanner(System.in);
String input = scan.nextLine();
char [] ch = input.toCharArray();
int count=0;
for (int i = 0; i < ch.length; i++)
{
if (ch[i]!=‘ ‘)
{
count++;
}
}
System.out.println(count++);
}
}
