Which of the following method calls are legal? a. mathMethod (x); b. mathMethod (y); c. mathMethod (x, y); d. mathMethod (x + y); e. mathMethod (12L); f. mathMethod (12); g. mathMethod (12.2); h. mathMethod (); i. mathMethod (a); j. mathMethod (a / x);

Option a, b, d, f, and j is legal method calls.

Explanation:

In the given question some information is missing, that is the method definition which can be described as follows:

Method definition:

int x = 2, y=3; / /defining integer variable

int mathMethod (int x) / /method definition

{//method body

int z=x+y; / /calculate value

return z; / /return value

}

In the given question option a, b, d, f, and j is legal, because these options follow the correct syntax, and other option were incorrect which can be defined as follows:

In option c, It is illegal because it accepts only one parameter. In option e, It is accepts long number, that's why it is illegal. In option g, It accepts float value, that's why it is illegal. In option h, It doesn't accepts any parameter. In option i, It isn't use in method.
