Answer:
Legal calls to the method mathMethod(int x) are
a. mathMethod(x);
b. mathMethod(y)
d. mathMethod(x + y);
f. mathMethod(12)
i. mathMethod(a);
j. mathMethod(a / x);
Explanation:
If the variables x,y and a have been declared as ints then those method calls are legal since in the declaration of the method, mathMethod(int x) Â it is to accept an argument of type int when it is called. Note that in option j, the integer division a/x will still yield an int.
