Answer 1

Answer:

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.
