Example of ConcurrentSkipListSet in Java
March 23, 2019
ConcurrentSkipListSet is used in concurrent threading environment. ConcurrentSkipListSet maintains the behavior same as TreeSet. The elements in ConcurrentSkipListSet can be accessed simultaneously and element's integrity will be maintained. ConcurrentSkipListSet does not affect the performance. All accesses are lock free and we do not need to worry for synchronization because it handles concurrent accesses.
ConcurrentSkipListSetTest.java
package com.concretepage;
import java.util.concurrent.ConcurrentSkipListSet;
public class ConcurrentSkipListSetTest {
ConcurrentSkipListSet<String> csls= new ConcurrentSkipListSet<String>();
class AddThread implements Runnable {
@Override
public void run() {
//adds specified element in the set
csls.add("A");
csls.add("B");
// returns the first element
String s1=csls.first();
System.out.println(s1);
//returns the last element.
String s2=csls.last();
System.out.println(s2);
}
}
class SubThread implements Runnable {
@Override
public void run() {
// removes the specified element from the set.
csls.remove("A");
}
}
public static void main(String... args) {
ConcurrentSkipListSetTest ob = new ConcurrentSkipListSetTest();
new Thread(ob.new AddThread()).start();
new Thread(ob.new SubThread()).start();
}
}
