How many of the following are legal declarations?
[][] String alpha; [] String beta; String[][] gamma; String[] delta[]; String epsilon[][];
B.
As with a one-dimensional array, the braces must be after the type, making alpha and beta illegal declarations.
For a multi-dimensional array, the braces are allowed to be before and/or after the variable name.
They do not need to be in the same place.
The remaining three are correct, and Option B is correct.
