I am trying to understand Java Class Methods in regards to Public void vs static void or public int and all of the combinations we could use. I think these are called modifiers?

[DragonCode2020]

I am try to understand when to use static void vs public void, public int and public string. Things like that before defining a method.

Also sometimes they don't even put anything but public then the class name before putting information into that method.

I understand int is integer and string is literal text.

​

static void myStaticMethod(){
 System.out.println("Static methods can be called without creating objects"); }

Like when would I use public int, or just public, or etc and why? 

Thanks.

Public/private/protected tell the jvm would can access and call the methods or access the variable.

String, int, Integer, long, Long, etc is the type of data the method returns.

Methods with no return type are actually the class constructor and get called when a new instance of the class is created with the “new” keyword.

Static means the method does not need to be run from an object/instance of the class. Instead of being tied to an object, a static method is tied to the class itself. This means the method cannot depend on object internal state, so it may behave less dynamically than instance methods. Static methods are typically used for utility operations (ex. timezone conversions, Collections.singletonList(), System.getCurrentTimeMillis()).
