Java Error Cannot Find Symbol Scanner


by this I mean declare import CLASS NAME, as I did when importing the Scanner class from the Java API... Another way is to ask the user to input a single number and put this code in a loop so the user is asked for a number, the number is added You will have to pretend that −123 is a single token representing a negative number, rather than what it really is, namely a positive number preceded by the sign change operator posted 2 years ago p.s. http://shpsoftware.com/cannot-find/java-error-cannot-resolve-symbol-class-scanner.php

Bluej Cannot Find Symbol Class Scanner

it may be far better if you could point me in the right direction by simply correcting my object reference variable c and it's deceleration so I can see what I've Just because something compiles, doesn't mean it works. How do you create an object that inpu will reference? I am greener then green as this is my first attempt to learn programming.

which seems strange since it compiles in my program, this is obviously where I'm confused. It is if (b)… or if (!b)… I understand why you mentioned using == is prone to error, however why is it poor style? BTW, as another note, it is not a good idea to have an instance variable of type Calculate class, that will be instantiated in the Calculate class. Java Cannot Find Symbol Class In Same Package I think you know that it returns a String.

Many beginners would have attempted to write all this in the main method of one class. Cannot Find Symbol Java Compile Error You can organise things so the input is 123 + 234 + 345 + 345 = although I may be incorrect we shall see! For example, consider the following program: public class Test { public static void main(String[] args) { myMethod(1.0, 2, "Hello!"); } public static void myMethod(double d, String s, int x) { System.out.println(s setUpCalc.java public class setUpCalc { public static void main(String [] args) { inou.numsToAdd(); inou.numsToOutput(); } } inputOutput.java import java.util.Scanner; public class inputOutput { inputOutput inou = new inputOutput(); public void numsToAdd()

David Thompkins Greenhorn Posts: 17 posted 2 years ago Hi Knute, when you wrote all classes are data types does that also go for classes which I make myself?

  3. input = new Scanner (inFile); } ... } Now input is not limited to the scope of the constructor, it'll be accessible through the whole class.
  4. You come across inou.
  5. Also, you can do this without using the import statement, although I don't recommend: java.util.Scanner scanner = new java.util.Scanner(System.in); In this case, you just directly tell the compiler about which Scanner

If the solution to fix the deceleration for lets say reference variable c... I believe it is the only package that is. (Can anyone confirm?) Apologies for all of those questions Knute I just what to ensure I understand, No apology necessary.
