Answer / aravinda reddy
ArrayList is by default not thread safe, but we can make it
thread safe. Below is the example how we can make it thread
safe.
public class SynchronizeList {
public static void main(String[] args) {
ArrayList<String> al=new ArrayList<String>
();
al.add("1");
al.add("2");
al.add("3");
//we can make the synchronized
Collections.synchronizedList(al);
synchronized(al) {
Iterator i = al.iterator(); // Must
be in synchronized block
while (i.hasNext())
System.out.println(i.next());
}
}
}
Vector and HashTable are by default synchronized. These are
thread safe.
Hence the answer is ArrayList.
