Java ConcurrentSkipListSet clone()用法及代碼示例


java.util.concurrent.ConcurrentSkipListSet的clone()方法是Java中的內置函數,該函數返回此ConcurrentSkipListSet實例的淺拷貝。

用法:

ConcurrentSkipListSet.clone()

參數:該函數不接受任何參數。


返回值:該函數返回ConcurrentSkipListSet的淺拷貝。

以下示例程序旨在說明ConcurrentSkipListSet.clone()方法:

示例1:

// Java Program Demonstrate clone() 
// method of ConcurrentSkipListSet 
import java.util.concurrent.*; 
  
class ConcurrentSkipListSetCloneExample1 { 
    public static void main(String[] args) 
    { 
  
        // Initializing the set 
        ConcurrentSkipListSet<Integer> 
            set = new ConcurrentSkipListSet<Integer>(); 
  
        // Adding elements to this set 
        for (int i = 10; i <= 15; i++) 
            set.add(i); 
  
        // Printing elements of the set 
        System.out.println("The set contains: " + set); 
  
        // Cloning the ConcurrentSkipListSet 
        ConcurrentSkipListSet<Integer> clone_set = set.clone(); 
  
        // Adding elements to the clone set 
        clone_set.add(16); 
  
        // Printing elements of the clone set 
        System.out.println("The clone set contains: " + clone_set); 
    } 
}
輸出:
The set contains: [10, 11, 12, 13, 14, 15]
The clone set contains: [10, 11, 12, 13, 14, 15, 16]

示例2:

// Java Program Demonstrate clone() 
// method of ConcurrentSkipListSet */ 
import java.util.concurrent.*; 
  
class ConcurrentSkipListSetCloneExample2 { 
    public static void main(String[] args) 
    { 
  
        // Initializing the set 
        ConcurrentSkipListSet<String> 
            set = new ConcurrentSkipListSet<String>(); 
  
        // Adding elements to this set 
        set.add("Gfg"); 
        set.add("is"); 
        set.add("fun"); 
  
        // Printing elements of the set 
        System.out.println("The set contains: " + set); 
  
        // Cloning the ConcurrentSkipListSet 
        ConcurrentSkipListSet<String> clone_set = set.clone(); 
  
        // Adding elements to the clone set 
        clone_set.add("site"); 
  
        // Printing elements of the clone set 
        System.out.println("The clone set contains: " + clone_set); 
    } 
}
輸出:
The set contains: [Gfg, fun, is]
The clone set contains: [Gfg, fun, is, site]
