Add the five numbers; divide the result by 5.

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
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();
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));}}
== == 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.
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.
Using toString() method
The best method is to add the numbers, using arithmetic.

by using the Gamma method apparently...:)

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.
