Foreach loop in java for Dictionary

Question

I want to go through every items in a dictionary in java. to clarify what I want to do, this is the C# code

Dictionary LableList = new Dict         


        

Answer 1

Your best bet is to use this:

for (String key : LableList.keys()) {
    Label value = LableList.get(key);

    // do what you wish with key and value here
}

In Java however, a better bet is to not use Dictionary as you would in .NET but to use one of the Map subclasses, e.g. HashMap. You can iterate through one of these like this:

for (Entry e : myMap.entrySet()) {
    // Do what you wish with e.getKey() and e.getValue()
}

You are also advised against using Dictionary in the official javadoc.
