We want to refer to the instance

variable strName inside the

method, but this code fails!

WRONG!

Preventing Identifier Ambiguity

Given:

class Person

{

String strName;

. . .

public void setName (String strName)

{

strName = strName;

} // of setName

Inside the method, the String strName

refers to the String in the method signature.

This creates a problem:

which strName is which?
