What does intern() method in java?
The intern() method of the String method returns a canonical representation for the string object. A pool of strings, initially empty, is maintained privately by the class String.
For any two strings s and t, s.intern() == t.intern() is true if and only if s.equals(t) is true.
All literal strings and string-valued constant expressions are interned.
Example
import java.lang.*;
public class StringDemo {
public static void main(String[] args) {
String str1 = "This is TutorialsPoint";
// returns canonical representation for the string object
String str2 = str1.intern();
// prints the string str2
System.out.println(str2);
// check if str1 and str2 are equal or not
System.out.println("Is str1 equal to str2 ? = " + (str1 == str2));
}
}Output
This is TutorialsPoint Is str1 equal to str2 ? = true
