Im currently working on an app that will work kind of like a quiz. What I am trying/hoping to accomplish is to have a random sound file played and have a couple of options to correctly match to the sound clip. The biggest problem I am having is calling the random sound file. I could get them to go in order but after a few times you could just memorize the answers. I was wondering if there was a way to randomly call a class or if there is a better way that I may not be thinking of. Kind of hit a wall and any help would be appreciated. Thanks in andvance Chpsrmne
You could use Java's Random Class and use its nextInt(n) function, with a switch statement to choose the next sound file and questions. Example code: (I didn't run this, should work though) Code (Text): import java.util.Random; public class YourClass { private static final int MAX_NUMBER=5; //number of sounds private Random rnd= new Random(); //declaring random number generator and initializing it private void choose () { //choose a random number from 0 to (1 below MAX_NUMBER) switch(rnd.nextInt(MAX_NUMBER)) { case 0: // if 1st sound is picked, do stuff break; case 1: // if 2nd sound is picked, do stuff break; case 2: // if 3rd sound is picked, do stuff break; case 3: // if 4th sound is picked, do stuff break; case 4: // if 5th sound is picked, do stuff break; //keep going until you have a case for each sound //in this case with MAX_NUMBER at 5, I would stop at 4 } } } Just add in the declaration and a similar method into the class you're using and that should work
