I was following the Java tutorial [this video] on freecodecamp and I wrote the following code. Here, I created two classes : PersonTest.java and Person.java. I have written 3 tests in PersonTest.java. While writing first two tests, two instances of Person class have been created. In the third test which counts the number of instances created; I am getting the output as 1 (I expect it to be 2). I am not getting why is it showing so. Any help is appreciated :) PersonTest.java package com.atharvajoshi.javacourse.lesson2; import static org.junit.Assert.assertEquals; import org.junit.Test; public class PersonTest { @Test public void shouldReturnHelloWorld() { Person atharva = new Person(); // First in
Cites laffytaffy · 2020-07 · Stack Overflow · on “How do I set this object's value? (Java 14)”
I am learning Java for the first time, and in the tutorial I am watching ( [this video] ), the instructor writes this code: private Name personName; public Person(Name personName){ this.personName = personName; } Does anyone know what the object 'personName' of the constructor class 'Name' does? How would I be able to set a value to 'personName' using the constructor 'Name' of class 'Name'? I would show you the code for 'Name,' but I don't know how to set it up so that the object of 'Name' would hold any value. Thanks for your help!
