completed the task but again unable to understand how line no 16 is working

Question about the task

Under discussion

how int month the passed argument passed inside checkSeason(int month) is working for all of the checkSeason() inside main()

Write the checkSeason method. Based on a number representing a month, the method should determine and display the season (winter, spring, summer, autumn).

Example for number 2:
winter

Example for number 5:
spring

Hint: the numbers 12, 1, and 2 are winter months; 3, 4, and 5 are spring, etc.

Requirements:

The program should display text on the screen.
The main method should not call System.out.println or System.out.print.
The main method must call the checkSeason method.
The checkSeason method must be static void, and have only one int parameter.
The checkSeason method should display text on the screen in accordance with the task conditions.

package com.codegym.task.task04.task0411; /* Seasons on Terra */ public class Solution { public static void main(String[] args) { checkSeason(12); checkSeason(4); checkSeason(7); checkSeason(10); } public static void checkSeason(int month) { //write your code here if (month==12||month==1||month==2) System.out.println("Winter"); else if (month==3||month==4||month==5) System.out.println("Spring"); else if(month==6||month==7||month==8) System.out.println("Summer"); else if(month==9||month==10||month==11) System.out.println("Rainy"); } }

line 16 is the method declaration. let's break it down a bit: 1) public - this is an access modifier (irrelevant here) 2) static - this means the method belongs to the class and not an instance of the class (irrelevant here) 3) void - this means the method does not return a value (irrelevant here) 4) checkSeason - method name. This is how you call the method (like it does on lines 10/11/12/13) 5) int month - this means that the method takes an int value as an argument. Whenever you call the method, you have to write an int in the parentheses. The fact that it is called month is irrelevant - it could be called "hsdhsjdh73773gdg" if you want (but that would be daft). Then the method body(lines 18-25) is the actual code executed whenever the method is called. And what the method will do, will depend on the passed value (month)

Thanks a lot please resolve one more issue of my ide. when i execute this program using intelliJidea. It shows the method call on lines 10/11/12/13 as checkSeason(month: 12) checkSeason(month: 4) checkSeason(month: 7) checkSeason(month: 10) What is this month here and why its showing so?

the month if you notice is greyed out. This is not actually part of the code but IntelliJ knows that on line 16 the value is named month. In this particular example you can clearly see the checkSeason method, you know what it does, and there's only one passed argument. Imagine instead you were using a method from a different Class, and you couldn't see the actual method. Imagine that method took multiple arguments You would have no idea what each passed argument actually referred to and how it was used in the method. That's where this comes in use - IntelliJ tells you the name of each passed argument, so you know which value to use where For example...

Let's say you have a Human class:

public Class Human {
String firstName;
String secondName;
int age;
int height;

public Human (String firstName, String secondName, int age, int height) {
this.firstName = firstName;
this.secondName = secondName;
this.age = age;
this.height = height;
}
}

In your own Class (Solution), you want to create a human object:

public Class Solution{
public static void main(String[] args){
Human human = new Human("John", "Doe", 20, 180);
}
}

How do you know that it should be

Human human = new Human("John", "Doe", 20, 180);

How do you know how many arguments should be passed? maybe it should just be

Human human = new Human("John", "Doe", 20);

How do you know what order they should be in and what each argument refers to? Because as soon as you write: Human human = new Human( IntelliJ prompts you that the first argument should be a String and refers to the first name of this Human Object. The second argument is also a String and refers to the second name of this Human object. That's why it's important to name the arguments in your methods properly
