Learn Java - Exercise 01x - Methods in Java

[@dmg-s]

I don't have any kind of method to return my "Gratitude" into your method.. It's all void.
UR THE BEST

[@lavexitosh]

The best out there on this topic!

[@miracielmurillo9574]

You can also switch case and call the methods from another class.

[@jeanjulmis2347]

I am glad I tried the exercises first. I used method to write my code since we are learning about method. If anyone wants to see my code, I'll post it.

you have made java interesting for me, just when i was almost giving up on it..can't seem to find anything on arrays. if you could please help with that as well... Bless up.

Can i buy the whole volume in Blu-Ray?

[@MathAndScience]

Sorry I don't make them on blu-ray. For the highest resolution, visit www.mathtutordvd.com and you can purchase the set as a download. Thank you!

very well explained

to every CS student checking the comments to see if this is worth watching

i spent a while trying to add a way to send an error message if you type something other than an integer but could not work out what structure it would work in

[@andreirotaru.c]

import java.util.Scanner;
public class JavaLearn {
public static void main(String[] args) {
Scanner sezoane = new Scanner(System.in);
int numar = 1;

System.out.println("Pentru fiecare sezon on parte scrie de la 1 la 4");
numar = sezoane.nextInt();
if (numar == 1) {
printPrimavara;
if (numar == 2) {
printVara();
if (numar == 3) {
printToamna();
if (numar == 4) {
printIarna();
}
public static void printPrimavara () {
System.out.println("Este primavara si este totul numai flori");
}
public static void printVara () {
System.out.println("Este vara si caldura este infernala");
}
public static void printToamna () {
System.out.println("Este toamna, iar frigul si frunzele se lasa");
}
public static void printIarna () {
System.out.println("A venit iarna si zapada este prezenta peste tot");
}
}
What is wrong here because does not work

[@ryanchau103]

You do not need an opening bracket for each of the if statement. It is reading as a single line.
