Java String intern Method

The Java intern method is one of the String Methods, which is to return the canonical representation of the string object. In this article, we will show how to write the String intern method with an example. The syntax of the intern in the Java Programming language is

public String intern();

//In order to use in program
String_Object.intern();

Java String intern Example

Here, We are going to use the intern method to return the canonical value of the user-specified string.

First, we declared two variables str1, str2, and assigned corresponding values using the first two Java statements.

Next, we declared two String objects str3, str4, and assigned a non-Unicode text values.

The last four System.out.println statements call the intern String Function to return the canonical representation of the above-specified string (str1, str2, str3 & str4)

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());
	}
}
