Haha u r funny sir "u r also dangerous"...I love ur videos so unique and knowledgeable

ratan sir ,very well done and noted always believe on practical knowledge.

Thank you Sir for amazing classes....

excellent sir I learned perfectly total class and let me know I need total core java videos by ratan sir

Thank you Ratan. These classes are very helpful.

Nice teaching,sir

Thank you very much Sir for making it all so simple. :-). But a small correction I would like to make that the static blocks are executed without main up to Java 1.6 and from 1.7 onwards, the main method is mandatory. Anyways, thank you once again for the wonderful class.

Awesome !!!!

Variables loads first (Both Static & Instance) Static Block loads after variables and it then executes Instance Block executes when the Object of the class is created. Constructor executes after the Instance Block after creating the object. Most important thing is Variables are the first one to load, they load before static block.

i never felt bored awesome explanation

Ratan is the most dangerous Java trainer in the world

your java tutorials are really very helpful

sir your explanations are just superb , keep it up

mr.Ratan, upto 1.6 version => we can execute some statements without main method. but from 1.7 version=> main method is mandetory to execute some statements.

Very nice explanation

U r videos are awesome sir

Hello sir, thanks a lot for helping us to understand the concepts easily. I have a small doubt, can we call the instance variables directly in the static block. If yes can you please explain how?

Ratan sir Ur Telugu person? Am I correct??

sir please upload the deleted video. It may helpful.

thnx alot for these video tutorials..

great videos...easy to understand

You are awesome sir

Best trainer.......(:-

Thank you ratan sir

very valuable video sir , sir forname method is not working on my pc sir i have checked multiple times by own

Really great one ji

class InstanceVariables {//class block begin int a=10; //instace variable /* Static block code executes only once during the class loading. The static blocks always execute first before the main() method in Java because the compiler stores them in memory at the time of class loading and before the object creation. */ static { System.out.println("in the static block a=" +new InstanceVariables().a); } /* During the object creation time, if any instance blocks are there, First instance blocks will be executed before the execution of any constructor. */ { System.out.println("in the instance block a=" +a); } /* A Java program will automatically create a constructor if it is not already defined in the program. It is executed when an instance of the class is created. */ InstanceVariables() { System.out.println("in the constuctor a=" +a); } public static void main(String args[]) {// main method will begin System.out.println("in main block a= " +new InstanceVariables().a); new InstanceVariables().m(); m1(); }//main method ends void m()//non static method { System.out.println("in non static method a= " +a); } static void m1()// static method { System.out.println("in the static method a=" +new InstanceVariables().a); } }//class block ends //OUTPUT /* in the instance block a=10 in the constuctor a=10 in the static block a=10 in the instance block a=10 in the constuctor a=10 in main block a= 10 in the instance block a=10 in the constuctor a=10 in non static block a= 10 in the instance block a=10 in the constuctor a=10 in the static method a=10 */ whats wrong with my program. why static block is executing after the instance block??

forName is not showing while i create 2 class in one package. one class without main method and one with main method. while i try to search with . operator after class. then it not show forName function in suggestion. I am using eclipse ide neon2

tnq ratan sir

tqqq

RATAN SIR IS THE BEST IN JAVA

A very happy teachers day Ratan sir, for example of forName you done it in 1.5 version so forName is not working in my 1.8 version, is it ok or i have some problem? and in the last example if i dont give value to instance variable still the output is same.

Hi Ratan, the request i have is could you please help us know with examples in which scenarios the last 4 elements of class are used. I know the advantages but...... when it is ideal to use methods and when constructor?. In the same way when it is ideal to use instance and when static blocks. I hope this is a valid question. Thank you very much.

Sir can you please explain how to call a constructor defined in another class which does not contain the main method in another class containing the main method.

Hi Ratan, I am facing a problem using forName method. It raise the same exception ClassNotFoundException but after use `throws ClassNotFoundException` still it i showing same exception. Below are my code and the exception:- My code:- public class A { static { System.out.println("class A static method"); } public static void main (String[] args) throws ClassNotFoundException //throws ClassNotFoundException { Class.forName("B"); // loading class B dynamically using forName method Class.forName("C");// loading class C dynamically using forName method } } // i have declared class B and C also using static method only But below is the exception message class A static method Exception in thread "main" java.lang.ClassNotFoundException: B

Ratan are these all classes will be useful for selenium automation. Please suggest me.

Ratan sir.. You are getting very dangerous at 14:39 😂😁 am I the only one who experienced this.?.. Anyhow thank you so much for your outstanding videos.. Keep doing.

Superb.

nice sir

why ClassNotFoundException occoured in last example(ie. dynamically calling other class) ? pls provide an answer for it.

Is it possible to assign static variable inside instance block?

Ratan Please mention forclass video name

superb

thanks sir

In the Last example, The output is : Static Block Instance Block 0 Arguement Constructor Instance Block 1 Arguement Constructor Instance Method Static Method Can you please explain why the Static Method is executed after the Instance Method ? Isn't it suppose to execute before the Instance Method if we go by the concept of Static Blocks being executed after .class files are generated and after that the Main method is executed where objects are created and hence the Instance blocks are executed. Why a change in concept during execution of Static Methods ?

I am not able to use of forName method in my programme. It always shows exception 'ClassNotFoundException'. How to resolve this issue?

tq sir

Hi sir

awesome!

In this lecture , i have problem in last example - when I'm creat constructor = Test () { system.out.println(0-arg cons) } in this line i have a compile time error " Invalid method decleration ; return type required" I'm using NetBeans IDE 8.2 for executing java program so please solve my problem

Superrr

Next continuation video emitu

public class static1 { static static1 d = new static1(); static { System.out.println("Inside Static block"); } { System.out.println("Inside Instace block"); } public static void jj() { System.out.println("Normal Static method..!"); } public static void main(String[] args) { System.out.println("Inside main method"); } } Output - Inside instance block Inside static block Inside main method

Isn't that Java 7 version onwords main method manditory

How to access private videos?

Class aypoindhi ...what is next video

I tried the last example about calling one static block form a class with no main method into another class with main method. But just can't seem to get rid of the error. class A { static { System.out.println("A class static block"); } public static void main(String[] args) throws ClassNotFoundException { Class.forName( "C" ); } } class C { static { System.out.println("C class static block"); } } not sure whats wrong since I am also catching the exception. out put is as follows: C:\Users\xxxx\Documents\MyJavaPrograms\RatanJava>java A A class static block Exception in thread "main" java.lang.ClassNotFoundException: C at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at A.main(A.java:10)
