Guys why is VSCODE unable to find main method when it's already there ?

static void sayHello(String name) {
    System.out.println("Hello"   name);
}

public static void main(Strings[ ]args) {
    sayHello("David");
}

A screenshot

I also tried adding a class but.. Didn't work.

second attempt

The thing with java is that you want every thing to be inside a class. and, remember this important bit - "the class name should match the file name." so, that is probably the issue. i.e. - in 1, code isn't inside any class. in second, the class name doesn't match the file name. if you are new to java, I suggest going through w3's java tutorial this is a text based tutorial so, you can keep your own pace or even speed run through it [do try out every thing they teach by yourself too]. I seriously recommend it since I started there and almost finished it within 1-2 weeks without any help.

S in String in public static void main(String[] args) { Should be in Uppercase.Error

CodePudding user response：

1. Your java file's name doesn't match the class name. Please rename your .java file as hello.java.
2. Pay attention to the args in main method should be String[], while it's Strings[] in your screenshot.
3. The white dot after your .java file means your file wasn't saved. Save it before running.

hello.java:

public class hello{
    public static void main(String[] args) {
        System.out.println("hello world");
    }
}

Please correct the above things, after Java: Clean Java Language Server Workspace from command Palette the run again.
