Error Cannot Find Symbol Scanner In = New Scannersystem.in

This means that if you declare a variable named average and try to later refer to it using Average, the compiler will complain that it cannot find a symbol named Average.

The most common example of this error is trying to assign a double to an int: public class Test { public static void main(String[] args) { int pi = 3.14159; System.out.println("The Therefore, simply delete one of the curly braces for the code to compile: public class Test { public static void main(String[] args) { System.out.println("Hello!"); } } expected Errors of the Cheers - Sam. Hi Knute, to clarify and ensure I understand what you've said.

setNums(total); //removed c.setNums(total); from the Calculate class. In that case see my answer above but ask the user for an operator and then ask for a number and call the appropriate method based on the operator. Ask on Piazza -- using the error folder.

cannot find symbol "Cannot find symbol" errors generally occur when you try to reference an undeclared variable in your code.

Except, on the third arrow, I tried making the equals sign (=) bold, but that didn't seem to do much. And since I have 6u12, that kind of puts me back into a problem when calling java.util.Scanner. Rather than read it in as a String and then try to interpret the value, the Scanner has an hasNextInt() method which might prove useful. I think (not certain) that the Scanner will interpret "−123" as a number and return a negative result, so you should be all right.

I am not able to generate a random picture. I'm guessing if using == true/false is bad practice then so is saying == to anything else? Raymond Holguin Ranch Hand Posts: 82 posted 2 years ago well everyone has there own way of learning, you can stick with yours and ill stick with mine. What are your thoughts?

For example: public class Test { public static void main(String[] args) { my_method(); } public static void my_method() { System.out.println("Hello, world!"); } 1 error found: File: Test.java [line: 9] Error: Test.java:9: trying to obtain user input and simply store the input inside a variable for now...

Since the main method is not closed, the compiler is expecting the line after the call to my_method to be a part of the main method's code.

  1. You may encounter a similar error if you forget to import java.util.Arrays or java.io.* when working with file input/output.

So what are your error messages when you compile? However, I have a question regarding line 7 img=img/255 I understand that it aims to scale the img value to 0 and 1. What is it?

For this error (and for many other errors), it may be necessary to look at the lines that come before the error to see where the problem is. However, the first line lets you know that a problem with a String index was encountered, and the index in error was -1. Thank you all for your excellent suggestions!

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 What do I need to do to fix this. Hi Knute, to clarify and ensure I understand what you've said.
