Why a static member method can access only static members in java?
Because, the keyword static signifies the fact that the method or variable that is qualified using the static keyword is not attached to any object of the class. Therefore we cannot instantiate the class and use the object to reference to access it. The only option we have is to use the class name to directly access them
Will JVM execute static methods by default like static variables in java?
No. Static methods are invoked by using the name of the class instead of the name of an instance of a class. Example: public class Test { public static void methodA { // do something ... } public void methodB { // do something else ... } } A program could use methodA by simply calling it using the class name: // call the static method Test.methodA(); To use methodB(), a program would have to first create an instance of the class then call the method: // call the non-static method Test t = new Test(); t.methodB(); Note that you can call methodA from the instance: // call the static method Test t = new Test(); t.methodA(); However, this is considered bad practice. And you cannot call methodB at all using the class name: // can't do this - compile error Test.methodB();
Static variable and static methods in java?
== == Static method cannot be overwritten because it belongs to the class and not to the ObjectIf you're asking about overriding or overloading, then yes. Static methods can be overridden and overloaded just like any other methods.
How do you sum up numbers from 1 to n?
import java.util.Scanner;public class average {static int i=0;static double sum = 0;static double average = 0;public static double calcSum(double sum){double count;Scanner input = new Scanner(System.in);while(i < 5){count = input.nextDouble();sum = sum + count;i++;}return sum;}public static double calcAverage(double average){double sum = calcSum(sum);average = calcSum(sum) / 5;return average;}public static void main(String[] args) {System.out.println("Please enter 5 numbers.");System.out.println("Sum is: "+calcSum(sum));System.out.println("Average is: "+calcAverage(average));}}
Tell about static method?
in java a method is said to be static if 'static 'keyword is used before the method name . foe ex.- static void show(){ ........ } this method has the following property-- 1. it can invoke only a static method. 2. it can't be reffered using keyword 'this','super'. 3.static method can access only a STATIC MEMBER VARIABLE or STATIC CLASS VARIABLE . 4. there should not be static & non static version of a nethod in a class . 5.static method can be used before the creation of d object of dt class.

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