Do While Loop

First of all, hey, Im a bit new to this board, and really needed help so thought it would be a good place to get some help.

Okay this is what i'm trying to do,

I want to create 50 random numbers assigned to different values, and tried using a do while loop for this.
E.g.

randomNumber1 = 34;
randomNumber2 = 43;

but without having to declare 50 numbers by hand, and rather have a loop to create it for me.

Here is the small bit of code for it that I wrote up:

Code :

---

int generateNum = 0;
int currrentValue = 2;
 
do {
      int randomNumber = (int)Math.round((Math.random() * 365) + 1); 
      }
 
while (generateNum < 49) {
 
       int randomNumber.currentValue = (int)Math.round((Math.random() * 365) + 1);
 
                    currentValue++;
                    generagteNum++;
       }

---

However upon compiling it gives the error message " ; expected " on the "while (generateNum < 39) {" line.



Anyone that can help me out of it?

Thats a very wierd piece of code if i do say so myself. Have a read up on Arrays, they will show you the light :D

Damn, didn't think about using an array. I think I should be able to do that quite easily. Thanks for the tip!

And btw, any chance you can elaborate on the 'weird' piece of coding? I'm more or less a complete newbie so any help to improve my coding is greatly appreciated :D

What is randomNumber.currentValue? never seen anything like it

... there should be a few compile errors in that code. do-while statements require a semi-colon after the while loop. Also, you're declaring two local variables with the same name (randomNumber). The int data type also doesn't have any sub-fields/methods, that's why it's a primitive data type in Java. Also, your do-while loop is generating a random number an infinite number of times without doing anything else. That will cause your program to hang, and also you really should do something each time a random number is generated.

What you want to do is something like this.

Code :

---

final int[] integers = new int[50]; // create the array to hold 50 primitive integers
final Random random = new Random(); // create the random generator, can be found in java.util package
 
// Loop 50 times and create a random number each time and assign it to the correct index in the array
for(int index = 0; index < 50; ++index) {
    integers[index] = random.nextInt(); // generate number and store in the array
}

I was trying to increment the currentValue by one each time, e.g. 1, 2, 3, then append it to randomNumber so it generates random variables like:

randomNumber1
randomNumber2
etc...

I think that functionality is with PHP which is why I got confused to why it didn't work.

And thanks Json, I already worked out a solution using arrays, which is similar to the solution you gave me. Thanks for the help though!

If there is a way to set this as solved, now would be the time to do it :D
