Java Program

Recommended Posts

You will be able to determine the answer by writing a small test program that compares the two variables.

 

Psuedo-ish code:

 

Main {

int Number = 10

int number = 5 //if Java recognizes N and n as different variables then you will get no error, otherwise you may get an error here.

 

//review output. if Number and number output is the same as what you initially declared then Java recognizes upper and lower case names as different vars.

printf("Number: ", Number, " number ", number )

}

A general tip - it's been helpful to me when learning a new language to answer these type of questions using similar small test programs.

... but note it's a very bad idea, unless part of a clearly understood naming convention.

 

For example, you might have a property named "Number" (e.g. name all properties with leading capital), and a method in the same class might have a locally scoped (meaning "visible" only inside that method) variable named "number". (This could still be a bad idea, depending on context).

 

But you definitely wouldn't want a method that has both "Number" and "number" as locally scoped variables, or a class with both of those as properties - too easily mixed up.

 

 

(Not a criticism of the preceeding example by Curiatron, which was only for illustration.)
