Java provides an easy method in java.utils.Collections class to

create a ThreadSafe collection from a regular collection.

We can use the method synchronizedCollection() for this purpose.

For any class of type T we can use following method:

static Collection synchronizedCollection(Collection

public class CollectionsSynchronizedCollectionExample3 {  
    public static void main(String[] args) {                 
        Collection<String> obj = new ArrayList<>();  
          obj.add("JavaTpoint"); // not thread safe  
          Collection<String> synObj = Collections.synchronizedCollection(obj);  
          synObj.add("SSSIT"); // thread safe  
          //Below iteration will result in non-deterministic behavior  
          Iterator<String> ite1 = synObj.iterator();  
          while (ite1.hasNext()) {  
              String s = ite1.next();  
              System.out.println(s);  
          }  
          //Below code is the right way to iterate synchronized collection  
          synchronized(synObj) {   
              Iterator<String> ite2 = synObj.iterator();  
              while (ite2.hasNext()) {  
                  String s = ite2.next();  
                  System.out.println(s);  
              }  
          }  
     }  
}
