Finding Length of string without using length() method In this article we’re going to make a Java program to find length of String without using length() method . In this program first we will take the String input from user . After that we will convert String to character array by using toCharArray() . After that we will use for-each loop to count the length of the String

length of string without using strlen Algorithm: In this program first we will take String input from user and store in the variable called s with the help of next() After that we will take a for-each loop and in the paremeter of for-each loop we will convert the String to character array using toCharArray() After that for every variable we will take a variable named as count and increment this every time Calculating Length of the string without using strlen() Code in Java Run import java.util.Scanner;

public class Main {

public static void main(String[] args) {
	int length=0;
	
            String s = "prepinsta";
            for (char c1 : s.toCharArray()) 
		length++;
	System.out.println("Length of String is : "+length);
	
}

} Output Enter a String prepinsta Length of String is : 9 Note The time complexity of this code is O(n) and if you are using the build in function like strlen or length the time complexity will still be same O(n)
