Java集合 synchronizedNavigableSet() 方法和示例

Java集合中的synchronizedNavigableSet()方法用于获取具有给定可导航集的线程安全可导航集。

句法：

public static  NavigableSet synchronizedNavigableSet(NavigableSet set)  

参数：

• set是输入的可导航集。

返回：它将从给定的输入（可导航集）返回同步的可导航集。

异常：它不会引发任何异常。

例子：

Java

// Java program to add elements
// to the Navigable set and convert
// them into the synchronized 
// navigable set with string data
import java.util.*;
  
public class GFG {
    // main method
    public static void main(String[] args)
    {
        // create an navigable tree set
        NavigableSet data = new TreeSet<>();
  
        // add elements into the set
        data.add("sravan-it");
        data.add("manoj-cse");
        data.add("sai-cse");
        data.add("vignesh-it");
  
        // get the synchronized navigable 
        // set from the above set
        Set final1
            = Collections.synchronizedNavigableSet(data);
  
        // display
        System.out.println(final1);
    }
}

输出

[manoj-cse, sai-cse, sravan-it, vignesh-it]

示例 2：

Java

// Java program to add elements to the Navigable
// set and convert into the synchronized 
// navigable set with integer data
import java.util.*;
  
public class GFG {
    // main method
    public static void main(String[] args)
    {
        // create an navigable tree set
        NavigableSet data = new TreeSet<>();
  
        // add elements into the set
        data.add(7058);
        data.add(4511);
        data.add(7859);
        data.add(4532);
  
        // get the synchronized navigable 
        // set from the above set
        Set final1
            = Collections.synchronizedNavigableSet(data);
  
        // display
        System.out.println(final1);
    }
}

输出

[4511, 4532, 7058, 7859]

示例 3：

Java

// Java program to remove an item
// from the synchronized navigable
// set
import java.util.*;
  
public class GFG {
    // main method
    public static void main(String[] args)
    {
        // create an navigable tree set
        NavigableSet data = new TreeSet<>();
  
        // add elements into the set
        data.add(7058);
        data.add(4511);
        data.add(7859);
        data.add(4532);
  
        // get the synchronized navigable 
        // set from the above set
        Set final1
            = Collections.synchronizedNavigableSet(data);
  
        // remove 4511 element
        final1.remove(4511);
        // display
        System.out.println(final1);
    }
}

输出

[4532, 7058, 7859]
