Map.Entry results in 'incompatible types' error

Followed the code in the Designing the UI video but getting this error on the for-each loop, specifically on this - Map.Entry<String, String> option

Error:(28, 62) java: incompatible types: java.lang.Object cannot be converted to java.util.Map.Entry<java.lang.String,java.lang.String>

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

        return choice.trim().toLowerCase(); // trim removes whitespace at beginning and end of String

Nevermind, I figured it out. Here's what was missing (in case anyone runs into this) -

My definition of mMenu was incorrect -

private Map mMenu;

and I fixed the issue by changing it to this -

private Map<String, String> mMenu;
