Thread: Not compiling...

I'm trying to run a simple code which is to just print out "Hello World", but whenever I run it, a message appears that reads: "Select a way to run Project_1(Which is the Java Project)"

The selections for it are: Java Applet and Java Application.

Whenever I click Java Applet it reads: Selection does not contain an applet.

When I click Java Application: Selection does not contain a main type.

Here is the code which I believe is correct:

package packag_1;
 
public class Num_1 {
	public static void main(String args){
		System.out.println("Hello World");
	}
}

Please help!

because you don't have a main method.
your method public static void main(String args) is not a main method for java,
java's main method should accept a parameter of String array not a String.
main method should be like this:
public static void main(String[] args) or public static void main(String args[])
args there is just the variable name, you can change it to whatever name you want.
