The Java String.intern method is one of the Java String Method which is used to return the canonical representation of the string object. In this article we will show you, How to write Java String intern method with example. Before we get into the example, let us see the basic syntax of the string.intern in Java Programming language is as shown below.
Java String intern syntax
The Java Programming Language provides an intern method to return the canonical representation of the user specified string.

public String intern(); // It will return String as output //In order to use in program String_Object.intern(); |
Java String intern Example
The Java String.intern method is used to return the canonical representation of the user specified string. In this Java program, We are going to the same.

// Java String.intern method example package StringFunctions; public class InternMethod { public static void main(String[] args) { String str1 = "We are abc working in abc company"; String str2 = "tutorialgateway.org"; String str3 = new String("A" + "\u00ea" + "\u00f1" + "\u00fc" + "C"); String str4 = new String("\u0048" + "\u0065" + "\u006C" + "\u006C" + "\u1D18"); System.out.println("Canonical representation = " + str1.intern()); System.out.println("Canonical representation = " + str2.intern()); System.out.println("Canonical representation = " + str3.intern()); System.out.println("Canonical representation = " + str4.intern()); } } |
OUTPUT
ANALYSIS
First we declared two String variables str1, str2 and assigned corresponding values using following statement
|
1 2 |
String str1 = "We are abc working in abc company"; String str2 = "tutorialgateway.org"; |
Next, we declared two String objects str3, str4 and assigned non-unicode text values using following statement
|
1 2 |
String str3 = new String("A" + "\u00ea" + "\u00f1" + "\u00fc" + "C"); String str4 = new String("\u0048" + "\u0065" + "\u006C" + "\u006C" + "\u1D18"); |
Following System.out.println statements will call the public String intern () method to return the canonical representation of the above specified string (str1, str2, str3 & str4)
|

System.out.println("Canonical representation = " + str1.intern()); System.out.println("Canonical representation = " + str2.intern()); System.out.println("Canonical representation = " + str3.intern()); System.out.println("Canonical representation = " + str4.intern()); |
