The Java String length Method is 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 how to find the length of a String using the Java string length method with an example. 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 to find its length.
Java String length example
The String length method returns the length of the user-specified string. In this program, we are going to declare a few string objects and then find the length of those strings using this String function.
//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
In this string length example, First, we declared the String variable and assigned a value using the following statement
String str = "Hello";
The following String function statement will find the length of the above-specified string. Here we are assigning the output to integer values because string length in java returns an integer value.
int str1 = str.length();
Next, we declared three more strings using the following Java statements
String str2 = "Tutorial GateWay"; String str3 = "Free Java Tutorial at Tutorial GateWay"; String str4 = "Java Programming Language";
The following System.out.println statements will call the public int length() method to find the string length and then print the output
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());
