This won't compile, whats wrong with it

[aqazwsx1]

This lets the user enter a min and max value, then ask the user too enter a number in the min and max number's range.

Java:

public class Prompter {            public static void main (String [] args) {                int num1,num2,num;                   System.out.println ("Enter a min number");         num1=input.nextInt();                 System.out.println ("Enter a max number");         num2=input.nextInt();                while (num>num1 && num<num2) {             System.out.println ("Enter a between "+num1+" "+num2);              num=input.nextInt();                      }               }    }

I got this error :


Prompter.java:8: cannot find symbol
symbol : variable input
location: class Prompter
num1=input.nextInt();
^
Prompter.java:11: cannot find symbol
symbol : variable input
location: class Prompter
num2=input.nextInt();
^
Prompter.java:15: cannot find symbol
symbol : variable input
location: class Prompter
num=input.nextInt();
^
3 errors

----jGRASP wedge2: exit code for process is 1.
----jGRASP: operation complete.


Can anyone help? Thanks!

Google java.io.InputStreamReader and java.util.Scanner for some hints.

Cheers

just wondering, is "input" something built into jGRASP?

maybe you'd like to put

Scanner input = new Scanner(System.in);

at the beginning?

First....have you imported the Scanner class from thee java libraries??
u hv to import it to use it.....
try typing this at the beginning(even before the class statement):

import java.util.Scanner ;

Then u should probably create an object called input before using it......use the statement SJ wrote.

Then it should work .
