Java Constructors

A class may have more than one constructor.

If so, then each constructor must have unique formal parameter list.

Constructor calls must match one of the available constructors

Terminology: Creating multiple methods with same identifier is called “method overloading.”

Given:

public String ( )

public String (String value)

We can:

String strInput1 = new String ( );

String strInput2 = new String

(“A valid constructor.”);

Such that:

strInput1 will be an empty

String (with the value ““)

strInput2 will be a String containing

“A valid constructor.”
