Random Value

Hey,

 

i have to generate a random value between 0 and 2 for a switch,

I've done it like this at the moment:

Random  rand = new Random();
switch(rand.nextInt(3))
{
     case 0:
     case 1:
     case 2:
  }

 

it should work (as far as i know) but its not ^^

It's always taking the last, the 2

Never 0 or 1

I'd like 2 know why :)

someone knows why?

 

 

Cheers,

-East

Like in other languages, switch statements in java "fall through", which means the following code:

switch (2) {
case 1:
    System.out.println("one");
case 2:
    System.out.println("two");
case 3:
    System.out.println("three");
}

Will print

two and three instead of just two. You need to explicitly break out of each statement:

switch (2) {
case 1:
    System.out.println("one");
    break;
case 2:
    System.out.println("two");
    break;
case 3:
    System.out.println("three");
    break;
}
