failing last requirement but seems to work

Question about the task

Under discussion

Using the System.out (which I've hidden to verify) it looks like this works. Not sure why it won't pass. any help please guys.

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; /* Census */ public class Solution { public static HashMap<String, String> createMap() { //write your code here HashMap<String, String> map = new HashMap<String, String>(); map.put( "Map1" , "All1" ); map.put( "Map2" , "All2" ); map.put( "Map3" , "All3" ); map.put( "Map4" , "All4" ); map.put( "Map5" , "All5" ); map.put( "Map6" , "All6" ); map.put( "Map7" , "All7" ); map.put( "Map8" , "All8" ); map.put( "Map9" , "All9" ); map.put( "Map10" ,"All10" ); return map; } public static int getSameFirstNameCount(HashMap<String, String> map, String name) { //write your code here int countName = 0; for ( HashMap.Entry<String, String> pair : map.entrySet() ) { if ( pair.getValue().contains( name ) ) { countName++; } else { } } //System.out.println( countName ); return countName; } public static int getSameLastNameCount(HashMap<String, String> map, String lastName) { //write your code here int countLastName = 0; for ( HashMap.Entry<String, String> pair : map.entrySet() ) { if ( pair.getKey().contains( lastName ) ) { countLastName++; } else { } } //System.out.println( countLastName ); return countLastName; } public static void main(String[] args) { HashMap<String, String> map = createMap(); getSameFirstNameCount( map , "All" ); getSameLastNameCount( map , "Map" ); } }

It looks like this code caught a bug in the validation as the getSameFirstNameCount() code should fail. The methods should find exact matches to the input variable. Lets say you wanted to find how many times "al" appeared in the map. This code would count anything that contained "al", such as "calvin", "allen", "alice" etc. It is funny that it passed the first name method but not the last name method. Make sure that your code only counts if the names match.
