    Default Having issues with understanding this Project

    I am stuck on a problem that I hope to help me understand. In pseudocode.....

    I have a username and password that is downloaded into a hashmap
    Map<Integer, String> map = new Map<Integer,String>
    the password has been downloaded with hash() to show a numeric value instead of the real password

    I download a list of possible passwords into a LinkedHashSet. This is where I get lost. Help me understand how with the equals() I can check the values that I iterate through against the map.getvalue(). Thank you for your input.

    I solved it.

    First sub string--> John
    First sub string's hashcode--> 2314539
    Second sub string--> 110182
    Second sub string's hashcode--> 1449559771
    shows size of hashmap 4
    ******************************
    If Key from HashMap equals the dictionary teststring's hashcode then..
    MATCHED!! Jane-Test string is two, teststring's hash value is 115276
