scanner.nextLine()
Hey, plz can u explain what scanner.nextLine() means...

Re: scanner.nextLine()
That statement shows a object reference: scanner being used to call a method: nextLine().
To see what that method does, read the API doc for the scanner class.

The code posted here on the forum are real life examples of the usage of that method.

Re: scanner.nextLine()
does scanner mean that you can type stuff?
Scanner scanner1 = new Scanner (System.in);
System.out.println("Can you type?");
scanner1.nextLine() //with this i can type and characters will appear - without this line no characters i type will appear.
Re: scanner.nextLine()
Did you read the API doc for the nextLine() method to see what it does? It is a method that returns a String.
Are you talking about what appears on the console window when you type something in?type and characters will appear
The use of the System.in arg in the constructor designates where the Scanner class will get its input from: the keyboard.does scanner mean that you can type stuff?

Re: scanner.nextLine()
Ok, yes i typed in the console window
and is that a yes for does scanner mean that you can type stuff?
Re: scanner.nextLine()
I'm not sure what you mean by "type stuff". When I open a command prompt window, I am able to type stuff into the window. It has nothing to do with java or using the Scanner class.
Using the Scanner class with System.in as its arg means that what the user types into the command prompt window will be read by the Scanner class's methods.

Re: scanner.nextLine()
Ok, basically when i take away the "scanner1.nextLine()"
characters dont appear in the console when i type them,
If scanner1.nextLine() is added, i can type characters into the console and they will show up.
Re: scanner.nextLine()
Interesting. I don't know what use typing characters on the console is.
The useful part is that what is typed on the console can be read into the program and used by the program.

Re: scanner.nextLine()

Re: scanner.nextLine()
