Given (we are reading it by the user) a string and we have to find its length using Java program.

To get the length of the string, we are using length() method of string class.

import java.util.Scanner;

public class ReturnLength
{
	public static void main(String[] args)
	{
		// create object of string and scanner class.
		String text;
		Scanner SC=new Scanner(System.in);

		// enter the string here.
		System.out.print("Enter the string : ");
		text=SC.nextLine();

		// find string length
		int length = text.length();
		// print length.
		System.out.println("Length of the given string " + text+ " is : " +length );
	}
}

First run:
Enter the string : Include Help
Length of the given string Include Help is : 12

Second run:
Enter the string : We are programmers.
Length of the given string We are programmers. is : 19
