loop for each Map Entry in Java

I'm having trouble trying to replicate the promptAction() method in the KaraokeMachine. I'm getting an error that says:

./com/teamtreehouse/KaraokeMachine.java:27: error: incompatible types: Object cannot be converted to Entry<String,String>
for (Map.Entry<String, String> option : mMenu.entrySet()) {

Apparently there's a type casting issue.

Here's my full method:

  private String promptAction() throws IOException {
    System.out.printf("There are %d songs available. Your options are: %n", 
    for (Map.Entry<String, String> option : mMenu.entrySet()) {
      System.out.printf("%s - %s",
    System.out.println("What do you want to do:  ");
    String choice = mReader.readLine();
    return choice.trim().toLowerCase();

I fixed my problem. It was with my Map member declaration.

I had this: private Map mMenu;

instead of this: private Map<String, String> mMenu;

The error message was fooling me and making me stare at the wrong line of code.
