I guess the mult you said should be a method name. It defines two integer parameters, and you can use * to return the product. Look at the code below.

Public? Class? test

{

Public? Static electricity int？ mult(int？ First,? int？ b)

{

Return? Answer? *? b；

}

Public? Static electricity Invalid? main(String[]？ Parameter)

{

int？ Answer? =? 1,? b？ =? 2;

int？ The result? =? mult(a，b)；

System.out.println (result); ? //? Output? 2

}

} I hope I can help you, and I hope to adopt it ~
