Thread: 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:

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

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

What is randomNumber.currentValue? never seen anything like it

What you want to do is something like this.

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
}

// Json

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
