Java LinkedHashSet clone()用法及代码示例

// Java code to illustrate clone() 
import java.io.*; 
import java.util.LinkedHashSet; 
  
public class Hash_Set_Demo { 
    public static void main(String args[]) 
    { 
        // Creating an empty LinkedHashSet 
        LinkedHashSet<String> set = new LinkedHashSet<String>(); 
  
        // Use add() method to add elements into the Set 
        set.add("Welcome"); 
        set.add("To"); 
        set.add("Geeks"); 
        set.add("4"); 
        set.add("Geeks"); 
  
        // Displaying the LinkedHashSet 
        System.out.println("LinkedHashSet: " + set); 
  
        // Creating a new cloned set 
        LinkedHashSet cloned_set = new LinkedHashSet(); 
  
        // Cloning the set using clone() method 
        cloned_set = (LinkedHashSet)set.clone(); 
  
        // Displaying the new Set after Cloning; 
        System.out.println("The new set: " + cloned_set); 
    } 
}
