Java compiler Error

Question

Hello I'm new to Java programming and well this is my following code...

public class Main {

  public static void main(String[] args) {

    System.out.println("Hello, World!");

  }

}

but when I try to compile I get the following error...

test.java:1: class Main is public, should be declared in a file named Main.java

public class Main {

       ^

1 error

I acuqire the following code from this website http://www.learnjavaonline.org/

I'm using the Linux Ubuntu OpenJDK Development Kit (JDK)

I believe this is how you compile.

cristian@ubuntu:~/Java$ javac test.java

I'm new to Java so any tips or guides will be appreciated thanks.

Answer 1

Name your file the same name as the class. If the public class is Main, then your file must be named Main.java, not test.java.

Answer 2

Either that or change the name of the class to test (notice the lower case -- class name must match file name).

Answer 3

The name of your file and the name of your class must be the same. Either rename your file to "Main.class", or change your class to public class test

Answer 4

This should work:

public class Test {

  public static void main(String[] args) {

    System.out.println("Hello, World!");

  }

}
