Question about the task

Census

Java Syntax, Level 8, Lesson 8

Resolved

Kindly, someone help me to know what is the problem with the code

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() { //write your code here HashMap<String, String> map = new HashMap(); map.put("Jamila1", "Ka"); map.put("Jamila2", "K"); map.put("Jamila3", "Kapchela"); map.put("Jamila4", "Kapchelaaa"); map.put("Jamila5", "Ka"); map.put("Jamila6", "K"); map.put("Jamila7", "Kapchela"); map.put("Jamila8", "Kapchelaaa"); map.put("Jamila9", "Kapchela"); map.put("Jamila10", "Kapchela"); return map; } public static int getSameFirstNameCount(HashMap<String, String> map, String name) { //write your code here key int count = 0; for (Map.Entry<String, String> pair : map.entrySet()) { String key = pair.getKey(); // Key if ((key.equals(name))) { count++; } } return count; } public static int getSameLastNameCount(HashMap<String, String> map, String lastName) { //write your code here int count = 0; for (Map.Entry<String, String> pair : map.entrySet()) { String value = pair.getValue(); // Key if (value.equals(lastName)) { count++; } } return count; } public static void main(String[] args) { //System.out.println(getSameFirstNameCount(createMap(), "Jamila")); //System.out.println(getSameLastNameCount(createMap(), "Kapchela")); } }

You've switched methods. Last name is the key and the first name the value. It doesn't matter in which way you fill the map ;) For the validation Jamila is a last name
