What does java bytecode refer to?

The semantics of various variables, keywords and operation symbols in the source code are eventually compiled into multiple bytecode commands.

2. Example

//Main.java
public class Main {
    
    private int m;
    
    public int inc() {
        return m + 1;
    }
}
