how to covert each loop into simple for loop?

[Chitta Ranjan Mahato]

Dear Experts,

Please covert the below code into simple for loop.

public static HashMap<String, Integer> sortHashMap(HashMap<String, Integer> input)
	{
	    Map<String, Integer> tempMap = new HashMap<String, Integer>();
	    for (String wsState : input.keySet()){
	        tempMap.put(wsState,input.get(wsState));
	    }

Thanks in advance.
Chitta Ranjan .

If I tell you that a for-each loop over a java.lang.Iterable (because that's what's being used in the for-each loop, not java.util.Collection, java.util.List or java.util.Set; those all extend java.lang.Iterable) uses the java.util.Iterator returned by the iterator() method, can you perhaps find the answer yourself?

Why do you want a loop in the first place? Go through the documentation for HashMap and yo ufind something useful.

[Shanky Sohar]

Yes i think there is no need of for loop here..Go through the HashMap documentation.

I don't understand the question. That for loop looks about as simple as it is possible for a for loop to be.

I think Chitta wants a for-loop like those of Java 1.4 and before. Having to migrate existing code from Java 5.0/6 to Java 1.4 (for whatever reason) is the only reason I can think of for wanting to convert this loop.

or it's a simple homework problem

I don't know, it doesn't look like homework to me. But on the other hand I would hate for that code to be real-life production code too.

Well, that's part of the reason why I only posted a hint and didn't type out the complete solution.
