JavaTutorial#4 Switch statements--fun :D

Okay. I assume you've read and understand the topic i posted about what you need to do before you even attempt any of my tutorials.

If you havent, Please read it here so i dont have to worry about useless errors -_-
______________________________________________________________________

I want to get one more done before i go to bed.

So here it goes--

We start out naming our class and typing that long line of random words lawl.

Code:

class SwitchStatTut {
    public static void main(String[] args) {

From here, we start out by declaring our initial day number.

For this it will be 3

Code:

int day = 3;

Now, we initiate our switch statement.

Code:

 switch (day) {

Always put your variable name in the parenthesis, If you were to declare your variable like int country = 4;, you'd put switch (country).

now we start the cases, This is where the numbers come in. Just in this tutorial, I'm going to have the cases--Days, 1=sunday, 2=mondy, 3=tuesday, 4=wednesday, 5=thursday, 6=friday, 7=saturday.

Code:

            case 1:  System.out.println("Sunday"); break;
            case 2:  System.out.println("Monday"); break;
            case 3:  System.out.println("Tuesday"); break;
            case 4:  System.out.println("Wednesday"); break;
            case 5:  System.out.println("Thursday"); break;
            case 6:  System.out.println("Friday"); break;
            case 7:  System.out.println("Saturday"); break;

The break; means if that is what the case is, to immediately stop. The reason we can use this here, is because we have System.out.println before, so it will print the the day when you run it.
So, Now you should have.

Code:

class SwitchStatTut {
    public static void main(String[] args) {

        int day = 3;
        switch (day) {
            case 1:  System.out.println("Sunday"); break;
            case 2:  System.out.println("Monday"); break;
            case 3:  System.out.println("Tuesday"); break;
            case 4:  System.out.println("Wednesday"); break;
            case 5:  System.out.println("Thursday"); break;
            case 6:  System.out.println("Friday"); break;
            case 7:  System.out.println("Saturday"); break;

Just close all your brackets and you're done, You can change the number in int day=3; to anything, as long as its 1-7.

If you want, You can add default: System.out.println("invalid number"); break;

at the end if you are afraid you're gonna put the wrong day number. Or if you wanna play around with it.


Just remember to close your brackets.

Code:

class SwitchStatTut {
    public static void main(String[] args) {

        int day = 8;
        switch (day) {
            case 1:  System.out.println("Sunday"); break;
            case 2:  System.out.println("Monday"); break;
            case 3:  System.out.println("Tuesday"); break;
            case 4:  System.out.println("Wednesday"); break;
            case 5:  System.out.println("Thursday"); break;
            case 6:  System.out.println("Friday"); break;
            case 7:  System.out.println("Saturday"); break;
          default: System.out.println("invalid"); break;
        }
    }
}

umm, what is this?

@Henry, its Java code

Lawl. Yeah. JavaJavaJavaJavaJava

lol henry u dont know much

Henry=Anti-Tech-Friendly

lol henry is the nicest in the world

Lawl

Understand what?

o_O

I'll help if you tell me what you mean.

yes i dont i want post anything here anymore LOL

lol

wait, then what does this do? what do i save it as?

Well, You'll have to download Dr.Java. Like the sticky& tutorial # 1 says.

If you read those, YOu should be able to figure out on your own :p

But, If you still have trouble, YOu can ask me.

hey can u help me make a server? o.o non hamachi
