You wil need this line on the top of your code in order to compile: import java.util.Scanner; This kind of import statement is very important. They tell the compile of which kind of Scanner you are about to use, because the Scanner here is undefined by anyone. After a import statement, you can use the class Scanner directly and the compiler will know about it. 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 you mean to use. share|improve this answer answered May 11 '11 at 4:08 lamwaiman1988 1,45983773 add a comment| up vote 4 down vote You have to import java.util.Scanner at first line in the code import java.util.Scanner; share|improve this answer answered May 11 '11 at 4:00 Eng.Fouad 67.2k40188294 thanks heaps, got it working now =) –James Blundell May 11 '11 at 4:26 add a com

Keskiner/E+/Getty Images By Paul Leahy Java Expert Share Pin Tweet Submit Stumble Post Share By Paul Leahy Definition: When a java error cannot find symbol class Java program is being compiled the compiler creates a list of all the identifiers in use. If it can't find what an identifier refers to (e.g., there is no declaration statement for a http://stackoverflow.com/questions/5959061/cannot-find-symbol-class-scanner-error variable) it cannot complete the compilation. This is what the cannot find symbol error message is saying, it doesn't have enough information to piece together what the Java code wants to execute.Possible Causes:trying to use a variable without declaring it.misspelling a class or method name (remember, Java is case sensitive).the parameters used do not match a method's signature.the packaged class has not being referenced correctly using an http://java.about.com/od/cerrmsg/g/Definition-Cannot-Find-Symbol.htm import declaration.Examples: The following code: System.out.prontln("The perils of mistyping.."); will cause a cannot find symbol error because the System.out class does not have a method called “prontln”: cannot find symbol symbol: method prontln(jav.lang.String) location: class java.io.printStream The two lines below the message will explain exactly what part of the code is confusing the compiler. continue reading below our video 9 Tips to Extend Your Phone's Battery Error Message Glossary:# A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Show Full Article Related Compile-time Error Understanding 'Overloading' In Java Parameter Statement More from the Web Powered By ZergNet Sign Up for Our Free Newsletters Thanks, You're in!
