下麵是說明clone()方法的示例：

範例1：

// 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 initalizing 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() mehtod 
            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); 
        } 
    } 
}

輸出：

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

範例2：

// 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 initalizing 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() mehtod 
            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); 
        } 
    } 
}

輸出：

equivalent object:- java.text.RuleBasedCollator@78930901
