How do I make a .jar file?

Hello, I want to learn java, and I got a book for it. Now, the book doesn't cover how to make a .jar file (i think), so how do i make one?

Are you using a build tool? Are you using an IDE? What do you want to create a JAR file for?

MrTomiCZOP•6d ago

no, no, System.out.println("Hello, World"); im just starting only thing i know is jshell

Then why do you want to create a JAR file?

MrTomiCZOP•6d ago

so i have an exec utalbe executable*

If you are just writing hello worldapplication, you probably don't want to deal with JAR files right now. But the first step is putting your code in a .java file and then you can execute it with java YourJavaFile.java

MrTomiCZOP•6d ago

so i just put the raw code there? or how

dan1st•6d ago

You'd create a main class and put your code there But if the book you are using starts with jshell, it should be included at some point there

public class test {
    public static void Main(String[] args) {
        System.out.println("teset");
    }
}

public class test {
    public static void Main(String[] args) {
        System.out.println("teset");
    }
}
