As you know there are two types of methods in PHP classes: static and non-static. To be called a non-static method needs an instance of its class, and static method can be called without instantiating of the class. In the meantime there are two very common questions:When to use non-...
Java permits you to override the non-static method. This type of method is created using the keyword “non-static”. In non-static methods, dynamic and runtime binding is utilized. As a result, we cannot call it without the class’s instance. In this case, memory is allocated whenever t...
Astatic method belongs to the class itselfand a non-static (aka instance) method belongs to each object that is generated from that class. If your method does something that doesn't depend on the individual characteristics of its class, make it static (it will make the program's footprint ...
Use static methods only if the method dependsONLY ON ITS PARAMETERS. If you're reading from the config, making database calls or communicating with an outside resource in any way use an instance method. Seriously, the performance difference between a static and non-static method is so small ...

2. static class is actually astatic memberof the class and can be used in thestatic context, like a static method or a static block of Outer class. 3. Another difference between static and non-static nested classes is that you can not access non-static members, like method and field, in...

In a large code base, however, the sheer number of call sites might make searching to see if it’s possible to convert a static method to a non static one too costly. Many times people will see the number of calls, and say “ok… I better not change this method, but instead create...
When you define a static method or field, it does not have access to any instance fields defined for the class; it can use only fields that are marked as static. Furthermore, it can directly invoke only other methods in the class that are marked as static; nonstatic (instance) methods ...
