Arrays

[Lawrence Buensalida]

How do I create and use arrays in j2me midp 2?

[Svend Rost]

As you do in J2SE (and J2EE for that matter).

Do you wish to make an array of anything specific, or was this just a general question ?

Thanks for the tip, though I'm just starting to learn Java, what you said is going to be helpful. Actually, I'm planning on creating an array for a set of 5 randomized numbers and I don't know if J2ME is capable of doing it, moreover, I don't know how to create and implement.

Hi,

Yes, it's possible to make random numbers in J2ME.

It's pretty simple to make an array. The following is a small
program for J2SE, which prints the values in an integer array.

public class ArrayTest
{
 int[] table = new int[4]; //integer array with 4 slots
 
  public static void main(String[] args)
  {
    table[0] = 10; // the first index in an array is 0
    table[1] = 20;
    table[2] = 30;
    table[3] = 40;
 
    printTable(); //method call to the printTable method/function
  }
 
  void printTable();
  {
   for(int i=0; i<table.length; i++) //loop
   {
     System.out.println( "printing: + table[i]); //print statement
   }
  }
}

If you insert the above code in a file called arrayTest.java, and compile
it (write the following in the prompt: javac ArrayTest.java), and then
run it with: java ArrayTest


The following is a small article concerning Random numbers in Java.
If your new to computing, it might be "a bit to much".

Alright! It worked in J2ME too. Thank you very much.
