How to get HashMap into SynchronisedHashMap
Here is an easy example that converts HashMap into SynchronisedHashMap. Its simple java
code but some time useful while handling multi Threads.
import java.util.HashMap;
import java.util.Collections;
import java.util.Map;
import java.util.Set;
import java.util.Iterator ;
class synchroHashMap
{
public static void main(String[] args)
{
HashMap hashMap = new HashMap();
hashMap.put("1","One");
hashMap.put("2","Two");
hashMap.put("3","Three");
Map map = Collections.synchronizedMap(hashMap);
// map can be use by mutipul Threads.
Set s=hashMap.keySet();
Iterator it=s.iterator();
while(it.hasNext())
System.out.println("Key are " +it.next());
}
}
Program Output .
Converted HashMap into SynchronisedHashMap and then got the Keyset of HashMap.
Key are 1
Key are 2
Key are 3
