Array constants can only be used in initializers

if you use the {...} array form in anything but an initializer.

 

WRONG

private int[] foo() { int[] x = new Array[3]; x = {1,2,3}; return x; }

 

 

RIGHT

private int[] foo() { int[] x = {1,2,3}; return x; }

 

ps:When using the initializers, an array must be declared, constructed and explicitly initialized at the same time.
