Make sure you have configured PATH, CLASSPATH and JAVA_HOME variable in system Environment variable.
1) It might refers older version of java then 1.5
or
2) May be not added PATH,CLASSPATH, JAVA_HOME variable there.
BTW Your code is works fine in my Eclipse.

I'm trying to import the scanner class into my program (I'm using NetBeans) but when I type "import java.util.Scanner;" I get an error that says "cannot find symbol: class Scanner"
I thought maybe I typed it wrong so I even copy and pasted the line from code on a different working project and it's still saying that. Not sure where to go from here. Anyone know what could be causing this error?

So, I just ran the code to see if it was just a glitch, and then it said an error message. Can you help? B.T.W. here's the error message Error: Could not find or load main class com.company.Main Caused by: java.lang.ClassNotFoundException: com.company.Main

The import goes here:
import java.util.Scanner;
public class JavaApplication2 {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Scanner reader = new Scanner(System.in);
// code here
}
}
It is not a property of the class but a reference the compiler needs to be able to tell what "Scanner" (in this context) refers to. In this case it states that Scanner is defined in java.util which is part of the Java Runtime Environment (JRE).
Furthermore as you go on coding you should structure your files into folders.
As soon as you do so you will have to add this type of line in the first line of the file: package folderName.folderName0.
If you want to use one of your classes from another one you will have to add an import like: import folderName.folderName0.JavaApplication2

You've put an entire java source file into a main function. Simply do this instead:
import java.util.Scanner;
public class JavaApplication2 {
public static void main(String[] args) {
Scanner reader = new Scanner(System.in);
}
}

December 14, 2025 -
I recently started learning Java and I'm having trouble understanding how this code works -
import java.util.Scanner;
class Program {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Input a number: ");
int num = in.nextInt();
System.out.printf("Your number: %d \n", num);
in.close();
}
}
Why do I need to know this? Top answer 1 of 5

You will understand with time, in java everything is a class and you are creating an instance of the scanner class and passing System.in as the parameter to its constructor. For now just know when you want the user to input something this is how you do.

It's a simple example of a program that takes in user input and displays it as output. I would expect whatever tutorial or curriculum you're following to go on to extend it to do more things. Most tutorials will start with command line programs like this, and knowing how to get user input is pretty important. Is there something specific about it you're struggling to understand?
Top answer 1 of 2

Yes, definitely a missing import. In general we would advise against importing whole libraries (eg. import java.util.* ) because you are adding a huge number of names that you don't know to your namespace. That can lead to really baffling errors when a name clashes (eg awt.List vs util.List), or even worse when you accidentally mis-spell a name and make a valid reference to some random class in java.util

I don't know Java, but are you importing java.util.Scanner or java.util.*?

August 30, 2022 - This is merely a warning that your IDE (Likely Eclipse) is giving you. It justs means you have added the import, but no one in your code is currently using the Scanner. If you write code to use the Scanner that warning will disappear.

November 12, 2019 -
The problem is basically stated in the title. I've tried everything I could think of and what I have found in Google but nothing could resolve my problem. I'm currently running Java 11.02 on IntelliJ community edition (but have also tried with 11, no success though). The "java.util.scanner" isn't even underlined with a wavy red, but instead the word "scanner" is shown in red, the title is underlined though.
Does anyone know what I could try?
