Why can't a String as a member variable??

CodePudding user response:

In addition to the constant is variable!
Variables are in the program is running can change the string class can, of course

reference 1st floor sotondolphin response:

why can't a String as a member variable??

if the other classes can also be as member variables

CodePudding user response:

What you said as a member variable is not a "String class
"But "String class" a "objects" of the "reference"

Such as a "members" of other classes,
We call this the "inner class
"
But I think, you said "members" most cases should only refer to "a class object reference"
