Java Thing Not Working? [HELP]

[Leon]

I made a program for the lols



There's a problem though when I launch the program it asks me the question. When I type something in it displays.

Exception in thread "main" java.util.InputMismatchException
at java.util.Scanner.throwFor(Unknown Source)
at java.util.Scanner.next(Unknown Source)
at java.util.Scanner.nextDouble(Unknown Source)
at base.Input.main(Input.java:11)

Any help??!?!?

You are putting a string into a double variable.

It works though :c

tryr inputing a different thing than a number. You'll get the exception then. It needs to be parsed and checked if it is a number.

Well yeah, obviously xD but I doubt that he knows exceptions catching though based on the simplicity of that code...

How do I create a string variable?

How do I create a string variable?

Bro, you can find that answer in like 2 seconds using google. But String string = "hi";

What doesn't work? Creating a string variable?

Got it working, thanks for the help!!!

package base;
import java.util.Scanner;

public class hello {
public static void main (String args[]){
Scanner scan1 = new Scanner(System.in);
System.out.println("Whats Raymond?");
String scan;
String raymond = scan1.nextLine();
System.out.print("Raymond Is A ");
System.out.println(raymond);
}

}

You could've easily done this if you're only looking for a double xD

package base;
import java.util.Scanner;
public class Input {
public static void main (String[] args){
  Scanner userinput = new Scanner(System.in);
  double raymond;
  System.out.println("Whats Raymond?");
  raymond = userinput.nextDouble();
  System.out.println("Raymond Is A");
  System.out.println(raymond + "");

As you can see, adding a ---> "" <--- to it makes it a String, but doesn't effect the final result at all.

I fixed the problem
