(Scanner)I dont really understand whats happening here and i use this alot.

Question

import java.util.Scanner;
//this imports scanner object right?

String x;
// x is telling system that x is a string //

Scanner scan = new Scanner(System.in);
//scan is telling the system that scan is the scanner object//

x = scan.next();
/*this is the part i dont get if x is now scan why do i ask systrem to print (x)?*/

//im assuming .next(); means after input read next line?

System.out.println(x);
// this retuns the input of x which is now a scanner?

Answer 1

*You create a Scanner, get input from the user and print it.

next() basically means to read the next word of input from the user. This would be until there's a space.
x = scan.next() is not making x a scanner. x is now whatever is returned from the next() method. Which is a String.
x = scan; is what would set x to a scanner. But this would throw an error since you can't convert a String to a Scanner.

The last line doesn't 'return' anything, it is only printing what the value of x is.

Answer 2

Edit the line x = scan.nextLine();

it's telling java that "read the keyboard input as a string .."

Answer 3

in Java, Scanner is a class name in Java.util package. basically used for input data from keyboard.
