Map did nit have 2 equals key...

Question about the task

Under discussion

For me the methods are ok but i didn't understand why the error?

Create a Map<String, String> and add ten entries that represent (last name, first name) pairs.
Check how many people have the same first name or last name.

Requirements:

The program should not display text on the screen.
The program should not read values from the keyboard.
The createMap() method must create and return a HashMap that has (String, String) elements and contains 10 entries that represent (last name, first name) pairs.
The getSameFirstNameCount() method must return the number of people whose first name is the same as the name parameter.
The getSameLastNameCount() method must return the number of people whose last name is the same as the lastName parameter.

package com.codegym.task.task08.task0815; import java.util.HashMap; import java.util.HashSet; import java.util.Map; /* Census */ public class Solution { public static HashMap<String, String> createMap() { HashMap<String,String> anagrafe = new HashMap<>(); anagrafe.put("nono", "panino"); anagrafe.put("pinone", "ginino"); anagrafe.put("tino", "panino"); anagrafe.put("sino", "panozzo"); anagrafe.put("pinozzo", "panino"); anagrafe.put("gino", "pappa"); anagrafe.put("pazzo", "capp"); anagrafe.put("cac", "capp"); anagrafe.put("cippa", "lippa"); anagrafe.put("cicco", "pasticio"); return anagrafe; } public static int getSameFirstNameCount(HashMap<String, String> map, String name) { int count = 0; for (Map.Entry<String,String> view:map.entrySet() ) { if(view.getKey().equals(name)){count++;} } return count; } public static int getSameLastNameCount(HashMap<String, String> map, String lastName) { int count = 0; for (Map.Entry<String,String> view:map.entrySet() ) { String k = view.getKey(); if(k.equals(lastName)) count++; } return count; } public static void main(String[] args) { } }

getSameFirstNameCount method please validate against the view.getValue() instead of the Key

It looks like this code is checking for equality among the keys, which according to the task is the last name. It should be counting the values instead.
