ints/how you can use them

xxdeadxx · 06-13-2009, 03:01 PM

Since most of the teaching tuts here area really just about how to start a server, or fill in the blank, I am posting this to hopefully help noobs use their own mind to help them code.

I am not going to be directly teaching you anything other then the basics of INTs and how they can help you.

Ok, So what is a Int you ask?

Int = Integer

A Int is just one of the many Java Methods that you can use to declare what you want.
Others include booleans, voids, strings, arrays etc.
What makes a int special though, is that it uses number rather then "words values".

A int can hold any number up to like 256000000 or something like that I don't know the exact number.

Ints are a great way to set up a better, easier and more extensive "true or false" statement.

For examples sake I will point you to my barrows tutorial. I needed to find a way to make it so that when you opened the chest, the brother would only jump out at you once. This is probably where I first started to really invest in ints. Realizing there potential after this.

Lets say you want to make it so when you click on a box it first says, "hello". Then the second time it says, "Boo"! Then the third time you click on it it will say "Pilldom rules"!

So the first step like any method is to declare it initially. This is all you have to do.

In your client.java declare this

Code:

public int exampleText = 0;

Easy. You might be asking how you make it say the different text with numbers? Its quiet simple when you get used to it really. If you where going to use my box idea then you would head over to your object click one and add....

Code:

case ####://the box ID
if(exampleText == 0) {
sendMessage("hello");
exampleText = 1;
} else if(exampleText == 1) {
sendMessage("boo!");
exampleText = 2;
} else if(exampleText == 2) {
sendMessage("Pilldom Rules!");
}
break;

Ok, now what exactly is this doing? Well that first bit of code we added the

Code:

public int exampleText = 0;

What that is doing is saying by default, the int exampleText's value is 0. Dosnt mean anything it just equals 0.

So when we added are second bit this is what it is doing

Code:

Line 1: if(exampleText == 0) {
Line 2: sendMessage("hello");
Line 3: exampleText = 1;

The first line is saying ok, if the int example text is 0, then initate lines 2 and 3. If its not equal to 0, then move on to the next if statement.

Line 2 is simply saying ok send the message hello.

Line 3 is the key part to this being effective. What line 3 does is say,"ok, public int exampleText is no longer equal to 0, it now equals 1". So when the next line after it comes

Code:

} else if(exampleText == 1) {

the int now equals 1 so it will do what is under if(exampleText == 1).

Horribly put, xxdeadxx.

Ints are a great way to set up a better, easier and more extensive "true or false" statement.

Each primitive data type has it's own specific function.

A Int is just one of the many Java Methods that you can use to declare what you want.

An int isn't really a method, it's a type.

What makes a int special though, is that it uses number rather then "words values".

Couple other primitive data types use numbers however unlike int, some can hold decimal's and numbers greater then what an int can hold.

What that is doing is saying by default, the int exampleText's value is 0. Dosnt mean anything it just equals 0.

This deceleration's value is set at 0 upon initialization of the class file. 0, can actually mean something if you give it meaning, however in this case it doesn't.

# int: The int data type is a 32-bit signed two's complement integer. It has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive). For integral values, this data type is generally the default choice unless there is a reason (like the above) to choose something else. This data type will most likely be large enough for the numbers your program will use, but if you need a wider range of values, use long instead.

Otherwise this is a good tutorial. Helpful, and there are some extra uses you should probably include.

ok thanks for the feedback

This was a very helpful post. Ive always wondered how to use ints for commands. Thanks for posting this rep++.

Also thanks to you I created cooking. :-).

do you even know who pilldom is..??

**AMG A Bear** · 06-16-2009, 04:44 PM

Code:

	case #:
		if(exampleText == 0) 
		{
			sendMessage("hello");
			exampleText = 1;
		} 
		else if(exampleText == 1) 
		{
			sendMessage("boo!");
			exampleText = 2;
		} 
		else if(exampleText == 2)
			sendMessage("Pilldom Rules!");
	break;

Much neater and a lot easier to read.

Ints are a great way to set up a better, easier and more extensive "true or false" statement.

How the hell is an Integer a better way to hold a true or false value when there is a type specifically for this? I find that amusing.

Also;

Code:

Others include booleans, voids, strings, arrays etc.

An array isn't a type, you have arrays of types if you understand that.

Put right an Integer or Int holds an Integer value(a whole number) between -2147m - 2147m(From the top of my head).

Sorry, useless tutorial.

Teach me about the variable 'char'

There are a lot of things wrong with your tutorial, however, good effort - at least you tried.
