Which one executed first static block or static methods in java?

Answer 1

Static Blocks are always executed first.

A static block is executed when your class is charged but a static method is executed only when is called, therefor first the class is charged and then is executed a method.

Answer 2

Static blocks and static methods in java are two types of class-level elements used for defining behavior that is associated with the class itself rather than the individual objects of the class. Therefore these both are executed at class-level, but there are some differences between the two.

Static blocks in Java are defined using the 'static' keyword and are executed only once when the class is loaded into the memory. They are used for initializing static variables or performing tasks that must be done only once, like reading configuration files or setting up a database connection. Static block is executed once when the class is loaded into the java virtual machine. It is used for initializing the static variables or performing any other one-time setup that needs to happen before the class can be used. A static block can be used to read configuration files or for initializing the static variables that depend on some external factors.

Below is the syntax of a static block

Public class NinjaClass{

 static{

  //code

}

}

A static method is defined using the static keyword, which is then followed by the method signature and method body. Static methods cannot access other static variables or methods of the class directly.

It is a method associated with the class instead of individual class objects. They can be called on the class itself instead of on an instance of the class. For accessing non-static variables or methods, we need to create an instance of the class and use that instance to access the non-static members.

Below is the syntax of static method:

Public class NinjaClass{

Static void SaticMethod(){

  //code

}

}

Due to the order in which Java initializes its classes, static blocks are executed before static methods. Static blocks are executed before any other code in the class when a Java class is loaded into the memory. Therefore, static variables that are initialized in the static block will be initialized before any static methods are called.Java ensures that static variables are initialized before any other code in the class is executed. Static methods can be called and executed once the static variables are initialized.

Therefore, Java developers need to understand the order in which static methods are executed for writing efficient code. In a class, static methods are executed in the order they appear. The execution depends on the order in which they are defined when the JVM loads a class. Static initializers are executed before any static method in the class.

Answer 3

A class has to be loaded in memory before we start using it. Static block is executed during class loading. This is the reason why a static block executes before the main method.

Answer 4

Static variable gets initialized first and then the static block gets executed.
