(2) is correct because the reference variables f1 and f3 refer to the same array object. (4) is correct because it is legal to compare integer and floating-point types. (5) is correct because it is legal to compare a variable with an array element. (3) is incorrect because f2 is an array object and f1[1] is an array element.
