Java: How to initialize int array in a switch case?

Solution
Put the declaration before the switch statement. You will also need to explicitly instantiate an array of the correct type.
int[] array;
switch (something) {
case 0: array = new int[] {1, 2, 3}; break;
default: array = new int[] {3, 2, 1};
}
Problem
How can I initialize an integer array in Java like so: `int[] array = {1,2,3};` inside a switch statement? Currently, I can write: ``` switch(something) { case 0: int[] array = {1,2,3}; break; default: int[] array = {3,2,1}; } ``` But when I try to access the `array` variable, eclipse will complain that it might not be initialized. If I try to declare it like `int[] array;` or `int[] array = new int[3];` and then have the switch statement, it would say I am trying to redeclare it. How can I resolve this issue? Final idea is to be able to initialize an array with 10 values in just one line of code, based on some logic (a switch statement).
