how to write array




now I'm developing calculation application.

while I'm developing my application, I wonder how to write array.


I want to use two random numbers by using array, so I write a code like this below.




     public Integer getRandomNumber1() {
          List<Integer> random = new Integer[2];
          random.set(0, Math.round(Math.random()*100));

          random.set(1, Math.round(Math.random()*100));


          return random.get(0);

          return random.get(1);




I need to return two random numbers in  getRandomNumber1 class.


Then I display two random numbers in a visualforce page.



I appreciate any advice.




You can't return two numbers with two return statements - your method will exit at the first return statement. Return the List of integers instead.


In your visualforce page use a dataTable or pageBlockTable to display the list.
