-

new java...

i have name class has:

private string firstname; private string middleinitial; private string lastname;

as instance variables.

if had data had firstname , lastname, no middleinitial, how make constructor took 2 parameters instead of three?

you write constructor 2 parameters , constructor three

public yourclass(string firstname, string lastname) {    ... }  public yourclass(string firstname, string middleinitial, string lastname) {     ... }

callers can choose use appropriate constructor based on needs.
