Class, interface or enum expected (Java)

Question

I'm a beginner programmer, I'm currently attending classes for programming in Java (and other things, it's an IT course). I'm currently copying some basic code for a very basic program from my notebook to NetBeans 8.1.

I made sure the code is EXACTLY as we did in class, I have a photo of the board, I've seen lots of people with this error here and it almost always seems like a few extra braces or these being put somewhere else they shouldn't be in.

I tried removing and adding and changing place but nothing works. This is my code:

public static int Mayor (int a, int b){
       if (a > b) {
           return a;
       }else{
           if (a == b){
               return -1;
          }else{
              return b;
          }
        }
}

Any help would be appreciated, thanks.

Java methods must be declared inside a class (as the error message says). Slides don't always display the whole code, but concentrate on the important part. You need to learn the syntax of the language. Read a Java book, and/or the Java tutorial. — JB Nizet, Sep 15 '18 at 20:06
That said, if you indeed pasted that verbatim, your teacher doesn't even respect the basic Java naming conventions, which is not a good sign. — JB Nizet, Sep 15 '18 at 20:07

For some additional reading you should take a look at [Java Code Conventions](http://www.oracle.com/technetwork/java/codeconventions-135099.html). A method name should not begin with a capital letter. — D.B., Sep 16 '18 at 00:16

Java does not have standalone methods. You need to wrap your function inside a class.

an example to Markus'es answer:

public class calss1 {
   public static int Mayor (int a, int b){
          if (a > b) {
              return a;
          }else{
              if (a == b){
                  return -1;
              }else{
                 return b;
              }
          }
    }

}

`а = -1` and `b = -2` => output is `-1`. So, what if we must consider these inputs? – zlakad Sep 15 '18 at 20:20
Thanks for the help, it did seem odd to me that it wasn't wrapped in a class, but like I said, I'm a beginner. – Moonfrost Sep 15 '18 at 20:26
