Java string length Examples [Multiple Scenarios]
Sometimes we might want to find the length of String in the Java programming language. For example, to validate the password, the first thing to do is to compare the total length, so in such cases, we need to find the length of an unknown String.
In this tutorial, we will learn how we can find the Java string length using the length method. We will also cover various examples and see how we can calculate the length of a string without counting the whitespaces and who we can calculate the total number of whitespaces in a string.
Moreover, we will also use the length method to find the length of the String typed Java array. All in all, this tutorial will contain all the important scenarios that you need to know to find the java string length for different purposes.
Getting Started with java string length
Before going into and finding the size of the java string, let us first recap java strings. So, a Java string is a sequence of characters that exist as an object of the class java. Java strings are created and manipulated through the string class. Once created, a string is immutable its value cannot be changed. You can read more from our article on «java string methods». Let us here see the syntax of strings in java through an example.
Syntax and example of a Java String
There are two ways to create String in java. The first method is using java literals. See the simple syntax below:
String name_of_string = "String Expression";
Another way to create a Java string is to create a String object from the Java string class. See the simple syntax below:
String name_of_string = new String("string expression");
Now let us take an example and create strings using both methods. See the example below:
Длина строки в Java. Метод length()
В этой статье мы поговорим про метод length() . Он позволяет определять длину строк в Java и сравнивать длины этих строк между собой. Давайте посмотрим, как это делается.
Описание метода
Вышеупомянутый метод length() возвращает длину строки в Java, при этом длина определяется, как равная числу шестнадцатиразрядных Юникод-символов в исследуемой строке. Метод использует довольно простой синтаксис:
Таким образом, возвращается длина последовательности символов. Но давайте лучше посмотрим, как это происходит на примерах.
Определяем длину строки в Java
Итак, у нас есть строка, в которой надо определить длину:
Консольный вывод будет следующим:
Длина строки " Добро пожаловать на сайт Otus.ru!" - 33 Длина строки " Otus.ru" – 7Вы можете проверить работу этого метода самостоятельно, используя любой онлайн-компилятор Java, например, этот.
Сравниваем длины строк в Java
Метод length() позволяет не только узнать длину строк, но и сравнить их длины. Вот, как это можно реализовать:
public class Main < public static void main(String args[]) < // Определяем длины строки s1 и s2. String s1 = "В Otus я стану отличным программистом!"; int len1 = s1.length(); String s2 = "В Otus я стану отличным разработчиком!"; int len2 = s2.length(); // Вывод на экран количества символов в каждой строке. System.out.println( "Длина строки \"В Otus я стану отличным программистом!\": " + len1 + " символов."); System.out.println( "Длина строки \"В Otus я стану отличным разработчиком!\": " + len2 + " символов."); // Сравнение длин строк s1 и s2. if (len1 >len2) < System.out.println( "\nСтрока \"В Otus я стану отличным программистом!\" длиннее строки \"В Otus я стану отличным разработчиком!\"."); >if (len1 < len2)< System.out.println( "\nСтрока \"В Otus я стану отличным программистом!\" короче строки \"В Otus я стану отличным разработчиком!\"."); >else < System.out.println( "\nСтроки \"В Otus я стану отличным программистом!\" и \"В Otus я стану отличным разработчиком!\" равны."); >> >Получим следующий результат:
Длина строки "В Otus я стану отличным программистом!": 38 символов. Длина строки "В Otus я стану отличным разработчиком!": 38 символов. Строки "В Otus я стану отличным программистом!" и "В Otus я стану отличным разработчиком!" равны.В результате метод length() позволяет нам как узнать длину строки, так и сравнить несколько строк. Но, как вы уже заметили, это был простейший код. Если же вы хотите прокачать навыки Java-разработчика на более продвинутом уровне, добро пожаловать на курс не для новичков:
Java - String length() Method
This method returns the length of this string. The length is equal to the number of 16-bit Unicode characters in the string.
Syntax
Here is the syntax of this method −

4 Methods To Find Java String Length() | Str Length
Java program to calculate length of string – In this article, we will discuss the various methods to calculate the length of a string, str length in Java programming. String length() java has been written in 3 to 4 different ways, you can check out here. If you any queries about source code str length in java, leave a comment here.
The methods used in this article are as follows:
- Using Standard Method
- Using Scanner Class (Predefined method)
- Using Scanner Class
- Using Static Method
- Using Separate Class
A string is a data type used in programming like an integer or a floating point but it is used to represent text whenever it is required instead of numerical.
As you can see, the string mentioned here is “Hello”. The string consists of 5 characters. All of the 5 characters are represented by a pointer. The location is represented by a pointer, in this case, starting from 0 to 4.
Similarly, other strings also have ideal lengths where the space between two words is also counted.
str length in Java – Using Standard Method
To find the length to string, we first taken in a string input in the code itself.
This string input is converted to a character array so as to traverse to the end of string individual character-wise to find the length.
To make this conversion, we can make use of a built in method for strings as below:
In this character array, we traverse until the end of the array in a loop and keep incrementing the count which is to be stored in a separate integer variable (a).
The end value of this variable (a) is nothing but, the length of our input string.
