NextLine();

Question

Choice = Scanner.nextInt();
Scanner.nextLine();

What does that mean?

Answer 1

reads your keyboard input whether string an integer

nextInt() > use for numbers
nextLine() > use for strings

Answer 2

nextLine() take the ENTIRE line of string input, rather than just the first word of the string. If you used next(), it would take the first word of the string.

Answer 3

/*below is all you need to use scanner with string and int*/

import java.util.Scanner;

//after main

Scanner scn = new Scanner(System.in);

//this space is ignored

String x = scn.nextLine(); /*< or use "int x = nextInt()" for int*/

//this space is ignored

If(x.equalsIgnoreCase("hello")/*< here use somthing like "x==20" for int*/{System.out.println("hey");}

/*dont look to much into spaces between your line of code this is called white space and is ignored unless you create white space inside a string is dosent matter*/

Answer 4

nextInt skips over white space to find the next integer storing it in choice. It will throw an exception when it finds something other than a number. nextLine returns a string containing everything left on the line, after finding the integer.

Answer 5

okay but they came after each others without and space between them?
