We are Known We are just live in Earth. The earth is a tiny piece of solar system. Solar system is a tiny piece of galaxy and etc.. etc... But, I would like to remember one think that's the world is not for only human. Its Also for other souls.like dog,cat,ant,trees fishes and etc... Human being are said humans are have better knowledge compared with other animals and souls.but, other animals and souls can't said iam best in the world. They are live these life joys full. The reson of joyful and happiness is these not have knowledge like human. The humans are said I am brilliant soul in the just piece of tempory living place is called earth or world or anything. Yeh I accept Humans are have better knowledge compared with others. But, human didn't have more knowledge compared with nature .  Because human or other souls are just a part of nature. Nature can survive with out humans. but human can able to with out nature?........ Nature System can give more knowl...

Solar radiation collectors are used to collect the solar radiations from sun. flat plate collector conducive collector Flat plate collector Its used to collect both beam and defused radiations. Can function  without track sun. Easy to contract and little maintains. Components of flat plat collector 1.Transparent cover(glass or plates) 2.black end observer 3.tubes 4.Thermal insulator 5.Tight container 1.Shadow effect shadow effect=surface of collector light observed/total surface of collector. 2.casino effect The ratio of angle between flat plat collector and sun orientation. 3.reflector effect Total reflection of solar radiation in flat plat collector.

constructor is a spacial member function of class. member function name and class name should be same is called constructor. it execute when object is initialize for that class. Eg: class A { void A() { System.out.println("constructor called"); } public static void main(String[] args) { A a=new A(); } } output: constructor called From the above Java code contains one class named as "A".then the class have two member functions one is "A()" and another one is "main()".Now the Member Function name and class name should be same its called as constructor.We initialize the object for class A inside the main method.then the constructor automatically executed. Types Of Constructor 1.Simple Constructor 2. Parameterized Constructor Simple Contractor The Constructor Does Not Pass Parameters. Parameterized Constructor The Constructor Pass Parameters. eg: class A { void A(int a) { System.out.println("Parameterized Constructor : ...

Inheritance is a future of oops(Object Oriented Programming).it Used To Share The Properties of Class or a class drive from another one class is Called Inheritance. in Java Programming "extends" Keyword is used to inherit the class. Syntax: class A{ //member variables and function } class B extends class A { //member variables and function } example, class A{ void superclass() { System.out.println("super class"); } } class B extends class A { public static void main() { B b=new B(); b.superclass(); } } From The Above Java Programming Contains Two Classes Named As "A" and "B".class A contains a Member Method Named as "superclass()" and class B contains main method.then class B is Inherit(Extends) From class A.So We are call The method superclass from class B.
