RuleBasedCollator clone() method in Java with Example

The clone() method of java.text.RuleBasedCollator class is used to get the copy of this Collator object.
Syntax:

public Object clone()

Parameter: This method does not accept any parameter.
Return Value: This method returns the copy of this Collator object.
Below are the examples to illustrate the clone() method:
Example 1:

Java

// Java program to demonstrate
// clone() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {

            // Creating and initializing new simple rule
            String simple = "< a < b < c < d";

            // Creating and initializing
            // new RuleBasedCollator Object
            RuleBasedCollator col
                = new RuleBasedCollator(simple);

            // getting copy of this object
            // using clone() method
            Object obj = col.clone();

            // display result
            System.out.println("equivalent object :- "
                               + obj);
        }

        catch (ClassCastException e) {

            System.out.println("Exception thrown : "
                               + e);
        }
        catch (ParseException e) {

            System.out.println("Exception thrown : "
                               + e);
        }
    }
}

Output:

equivalent object :- java.text.RuleBasedCollator@7033e09a

Example 2:

Java

// Java program to demonstrate
// clone() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {

            // Creating and initializing new simple rule
            String simple = "< a < c & a < b";

            // Creating and initializing
            // new RuleBasedCollator Object
            RuleBasedCollator col
                = new RuleBasedCollator(simple);

            // getting copy of this object
            // using clone() method
            Object obj = col.clone();

            // display result
            System.out.println("equivalent object :- "
                               + obj);
        }

        catch (ClassCastException e) {

            System.out.println("Exception thrown : "
                               + e);
        }
        catch (ParseException e) {

            System.out.println("Exception thrown : "
                               + e);
        }
    }
}

Output:

equivalent object :- java.text.RuleBasedCollator@78930901
