COMMAND LINE ARGUMENTS - JAVA PROGRAMMING

[@arjungautam1672]

Finally, you give a good concept. Thanks for sharing

[@sadbhavanadas6021]

Sir, really it's a great platform for learning Java.Can we get few list of questions for Java Programming which will be helpful to us to practice the codes

[@SK-gp6cm]

Bro can you send me practice programs

[@devesh8537]

Woww literally shocked by your teaching very clear explanation keep rocking bro🔥🔥

[@koradabhushan1548]

Sir you are really great for better explaination

[@ind-ram]

first view of this nice video

[@azharshaikh9642]

Wowww just amazing

[@kogilathotavijayreddy4963]

Your videos are helpful...

[@rohithbandi1652]

Sir you are super❤️ , concepts are easily understandable

[@anusrikamidri7299]

Ur explanation is so good sir Can u please give lecture on wrapper classes sir?

[@ind-ram]

makes more videos on java programming

[@virat4950]

excellent sir 👍👍😍😍

[@abhijitmondal9203]

What if I don't ever use any sort of command-line arguments....do I still need to mention the args[] as a parameter in main()? Because, in such case I don't see any need of this args[]. Thanks in advance!

[@manaligadre6690]

@Sundeep sir !! Can you please answer this question.

[@sundeepsaradhi]

hi even though you are not using any inputs through command line we have to pass an array args[] inside the main function. compiler will search the main with the format so we have to include this args[].

[@manaligadre6690]

Sundeep Saradhi Kanthety Got it!! Thanks sir :)

[@harinihar2468]

Thank-you for the q&a

[@SK-gp6cm]

@@sundeepsaradhi sir can you plz give me notes of Java and python plz

[@pdpaxpv]

Finally I understand String args[] lol...... Thanks!

[@rinkykumari4470]

Good explanation

[@amitkoushik5504]

Hello sir just a small correction at 9:41 ,we can save a java file with any name , there is no relationship between the file name and the class name consisting of the main method. The relationship is there between the public class name and file name , if a class is declared as public then only it's fine name should be the same as the class name. Thank you.

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0 at Add.main(Add.java:6)

[@vigneshwaran3540]

sir c is declare as integer by why you didn't write IntegerparseInt() function for variable since the system takes it as the string

[@sundeepsaradhi]

hi here c is the output variable so output is addition of two integers which will always be integer so we need not go for typecasting. Hope your doubt has been clarified.Thanks for your support towards our channel.

[@chandramohan9395]

Hi sir nice explanation I have a doubt If we give an input as 5 then the output should be five can u print this using clm??

[@fenil861]

Sir can we determine the size of args[] and what if we don't write the String args[] as arguments but we input numbers by scanner class. Will the program be successfully executed or there will be an error?

[@navyachenna683]

Yeah same doubt

[@krishnakumar-tw7cl]

But great explanation

[@sundeepsaradhi]

Thank you 🙂

[@ΧρυσοβαλαντηςΤασιοπουλος]

Excellent presentation ! So you can declare a main function inside a body of a class? In C that is not possible !!

[@nishanair3925]

sir, are these 2 arguments in main() the same String args[] and String[] args. Both are seen used

[@MohamedOsman-jh6ik]

Explain command line arguments

[@jeevithaswamy5741]

Hello sir, your explanation is good,but I have a doubt that can't we write the above program without type casting?

[@durgavyboina3896]

Sir, please do these core java classes in telugu sir..🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

[@gowthamigowthu1758]

Sir please explain lab practical programs factorial of list of numbers reading input as command line argument

[@adithyasundar2017]

Should we give command line arguments only in Main function

[@amulbabyentertainments6818]

How to get many command line arguments one by one in java. Like Input : hello Output: hii Input: how r u Output: fine

[@yellaadilakshmi5629]

@@KumaranKM Sir did you use thread concept?

[@harshithareddymanazipet260]

sir, if we write scanner in the function what changes will be made in output and input

[@pravinshinde3177]

if we are not using cmd(using eclipse) then we no need to write like integer.pareseInt(arg[]) please rectify my doubt.

[@sundeepsaradhi]

Hi Even though you are not using command line arguments the input is taken as string so we have convert the data type

[@durgavyboina3896]

Your teaching was fabulous but we can't understand in english so, please do in telugu sir..!🙏🙏🙏🙏🙏🙏

[@_random__vlogs_]

What is the usage or advantage of using this buffer reader?

[@sundeepsaradhi]

Hi Budferedreader is also used to take inputs from a file or keyboard

[@edhisangatulu]

Sir please upload tutorial on c program

[@ramneelavlogs]

hi sir im a begginer to java (sry about my silly doubts ): The command line argument passing you are refering to : is it the console in IDE or the actual command prompt in windows for the user to pass the value.

[@user-mb1gx5sb4d]

Its command prompt where we compile and execute the file(typed in notepad).

[@krishnakumar-tw7cl]

Subtitles is good sir but it is some disturbing to program is not visible in bottom so

[@saivivekkammari8851]

got an error. below is my code. Please tell me whats the mistake in my code class Add1 { public static void main( String args[2]) { int a,b,c ; a = Integer.parseInt(args[0]); b = Integer.parseInt(args[1]); c = a+b; System.out.println(c); } } #error Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 0 out of bounds for length 0 at Add1.main(Add1.java:5)

[@sundeepsaradhi]

Hi Vivek Not require to mention the size of argument array in main . So write public static void main(String args[ ]).

[@r-39amratprajapati76]

You are my god!

[@sivasiva5455]

Sir i am execute the program,it shows no error,but to run the program it shows ArrayIndexOutOfBound Exception can you clarify please

[@pixiedust..9789]

Sir, why is it a STRING ARRAY by default? Can it be int args[ ]? If not, why?

[@swamyvedurupaka4236]

Other to string conversion is easy and most of devlopers used string data type.

[@pdpaxpv]

String is universal. Suppose you write: java program 56 43 abc. It will throw an exception right there, because you declared args as int. But String will receive any value and parse it into anything you want.

[@backtoheaven9581]

hii sir what about System.err??

[@ravikumar-pw3zx]

Sir i have a big doubt why we use this CMD line simply we can use scanner class. ok we use this CMD then what is the advantage?

[@kamaleshs537]

Because...the time completion to run the program is lesser than compared to Scanner class.....

[@rishikasahu3319]

Sir, I write the same program in TCS DRC test, but it was showing arrayIndexOutOfBound error

[@srujanpalavarapu1520]

Same here, did you find the solution? Please explain if you got it.

[@sanm3338]

thank you !

[@knoorjahan226]

I have a doubt !! If we want to inform the user to enter valid data through commandline . How do we achieve that? Means validating user input and informing him to enter valid data if he enters valid data through commandline itself

[@danieltornero5523]

You can use try-catch

[@mohammedabrar6220]

Sir why you not show the program in eclips so we can easily understand it

[@jangammohankalyan8258]

When we run that program it was showing arrayindexboundexception

[@testingt9762]

Sir array declaration portions missing

[@sudarshanv9797]

there is one thing wrong in this video, that is we can't run .class file using java command. we can only run .jar file, because it has executable code of our program, .class file is just a compiled file, we can still read a .class file using java code editor, but we can't read a .jar file because it has bytecode in it.

[@chirusetturu63]

Gd after noon sir ,it shows error during compilation

Yes...here you must create an object using Bufferedreader,because there we typecasting the integer values to string.................hope u understand it....🙂🤗
