Java String: Exercise-20 with Solution
Write a Java program to get the canonical representation of the string object.
Sample Solution:
Java Code:
public class Exercise20 {
public static void main(String[] args)
{
// Create three strings in three different ways.
String str1 = "Java Exercises";
String str2 = new StringBuffer("Java").append(" Exercises").toString();
String str3 = str2.intern();
// Determine which strings are equivalent using the ==
// operator (as compared to calling equals(), which is
// a more expensive operation.
System.out.println("str1 == str2? " + (str1 == str2));
System.out.println("str1 == str3? " + (str1 == str3));
}
}
Sample Output:
str1 == str2? false str1 == str3? true
