    Default Displaying number of occurances of each word in the array

    The print statement is getting caught in the loop, but I'm not sure where to place the print statement. Am I close to the right answer in the last method, or should I erase it and start over with a different approach?

    If you print within the loop you will not get your desired output. That is because you can not forsee the future and you never know how many flowers of the same name might still come at a later position in the array.

    What you could do is have 2 for-loops. In the first loop you count the occurances, in the second loop you print them.
    The first loop would iterate over your flower array, count the flowers and populate a data structure used to save the results.
    The second loop would iterate over this other data structure and print the contents.
    The other data structure could be a Map<String, Integer> or something else entirely.

    Welcome to the Forum! Thanks for taking the time to learn to post code correctly, and if you haven't already, please read this topic to see other useful info for newcomers.

    I'm going to suggest you LOOK at the existing output, compare it to the desired output, and then review your code and correct it to achieve the desired output.

    You are printing the desired output and THEN SOME. Correct your code so that it stops printing the extra lines:

    Existing output:
    Daisy - 4
    Daisy - 3
    Daisy - 2
    Daisy - 1
    Rose - 2
    Rose - 1
    Sunflower - 1

    Desired output:
    Daisy - 4
    Rose - 2
    Sunflower - 1

    Examine your code and determine how to remove the extra lines.

    Please do not post a solution on this forum. Nobody is helped if you give away answers.
    People can only learn if they do something by themself.
