The Java String.length Method is one of the Java String Method which is used to find and return the length of the User specified string. The length is equal to the number of Unicode units in a string. In this article we will show you, How to find the length of a String using Java string length method with example.
Java String length Method Syntax
The basic syntax of the String.length in Java Programming language is as shown below.

public int length() // It will return the integer Value as Output //In order to use in program String_Object.length() |
- String_Object: Please specify the valid String Object.
Java String length Method example
The Java String.length method is used to return the length of the user specified string. In this Java program, We are going to find the same.

//How to find Length using Java String.length method package StringFunctions; public class StringLength { public static void main(String[] args) { String str = "Hello"; int str1 = str.length(); String str2 = "Tutorial GateWay"; String str3 = "Free Java Tutorial at Tutorial GateWay"; String str4 = "Java Programming Language"; System.out.println("The Length of a String Str = " + str1); System.out.println("The Length of a String Str2 = " + str2.length()); System.out.println("The Length of a String Str3 = " + str3.length()); System.out.println("The Length of a String Str4 = " + str4.length()); } } |
OUTPUT
ANALYSIS
First we declared the String variable and assigned a value using following statement
|
1 |
String str = "Hello"; |
Following statement will find the length of the above specified string. Here we are assigning the output to integer values because, java length method returns integer value.
|
1 |
int str1 = str.length(); |
Next, we declared three more string using the following statements
|
1 2 3 |
String str2 = "Tutorial GateWay"; String str3 = "Free Java Tutorial at Tutorial GateWay"; String str4 = "Java Programming Language"; |
Following System.out.println statements will call the public int length() method to find the string length and then print the output
|
1 2 3 |
System.out.println("The Length of a String Str2 = " + str2.length()); System.out.println("The Length of a String Str3 = " + str3.length()); System.out.println("The Length of a String Str4 = " + str4.length()); |
