Java problems (1 Viewer)

[Zambrotta]

I've got a really basic question on Java.

I want to randomize an integer between 0 - 100. I have some ideas but it should be simplier than how I made it.

Please help.

Does any of your suggestions actually work?

Is this a correct way to do it? (Can't test it myself on this computer unfortunately)

int r = Math.random()*100

I just tested this:

import java.util.Random;

class Jrand {

    public static void main(String[] args) {
        Random r = new Random();
        int randint = r.nextInt(10);
        System.out.println(randint);
    }

}

Dunno. I guess you could have not read it yet. Or not be a total nerd.

Seems neither applies to either of us.

What does "sudo" mean. I suppose that's the point of the story.

It's a linux command

A powerful one, one that can make someone make a sandwich for you

Yeah VB sucks but I think Java is nice.

 

[Zambrotta]

It's a linux command

But what does it mean?

"Probably" super user do, it basically gives access to any command, kind of like the key to the heavens I would call it the blue pill at certain days

Difficult stuff.


Another java question.

When I use
If statements sometimes I'm supposed to use ( == ) but sometimes people tell me it's better to have ( .equals ). I've never understood when.

You need to know the differences between primitives and objects in java. When you want to compare value between primitives you can use == operator. while the same case cannot be done with object.

The easiest example in this case is String,
String str1 = new String("value1");// create new object
String str2 = new String("value1");// create another new object
System.out.println(str1 == str2);/* will print false, because it compares whether str1 and str2 refers to same object.*/
System.out.println(str1.equals(str2));/* will print true, because the value of this two objects are equal*/
