Q. Java Program to find length of a given string.

Here you will find an algorithm and program in Java programming language to find length of given string. First let us understand string in Java.

Explanation : The string is defined as an array of characters. The difference between a character array and a string is the string ends with a special character '\0'.

For Example : If the string is "hello", then the output will be 5.

START
Step 1:Length = 0
Step 2: Repeat step 3 while S1 [Length] ≠ NULL
Step 3: Length = Length + 1
Step 4: Return Length
STOP

Java Program to Find the Length of a String

public class Main {
	public static void main(String[] args) {
		//declare the String as an object S1 S2
		String S1 = "Letsfindcourse";
		//length() method of String returns the length of a String S1.
		int length = S1.length();
		System.out.println("Length of the string = " + length);
	}
}

Output

Length of the string = 14
