9.3 User Input using System.in.read() method in java

[@sairajdas6692]

Sir since you did char type casting, it didn't print out the ascii value of Enter . Thank you sir btw for the video !

[@praveshmandloi9131]

hii sir thats nice way in that you have to write print except println.. then it wil run in right manner.. int i=System.in.read(); System.out.println("You have enter:"+(char) i); String str="";

[@MrYrpr]

I like your videos a lot Once I get a job, I will take paid course from you just as a way of saying thank you

[@adithyak7233]

Hi Navin,your teaching is really good, thanks a lot

[@aarushigupta1106]

sir yr contribution is anonymous .... thanku so much for clearing our doubts ... this really means a lots and lots of thanks a students trophy for a teacher infact the best teacher of java

[@SmartProgramming]

helpful video sir, thanks for this explanation 👍👍

[@CindyXin520]

thanks for the tutorial, helpful as always. comment out the initial value of int i and the code works: int i; // comment out initial value "int i = System.in.read();" String str = ""; while((i=System.in.read())!=10){ str = str + (char)i; } System.out.println(str);

[@mohanrammanikandan7939]

Hi, Cindy. Can you please explain how this loop works and the output arrives at "avin Reddy" finally ?

[@BoogieBash]

code inside of main: int i=32; String s1=""; while(i!=13){ i=System.in.read(); s1=s1+(char)i; } System.out.println(s1);

[@deepakpatra2011]

It also works with 10 instead of 13.

[@akarim3643]

Your lecture is really very helpful...Thanks a lot keep it up !!

[@rohitsoni9325]

Correct code for taking the input till user presses space key is::: System.out.println("Enter: "); String Str = ""; int i = System.in.read(); while((char)i != ' ') { Str= Str + (char)i; i = System.in.read(); } System.out.println("String is :"+Str);

[@mehrosenasir3966]

The object "out" of printstream class in not created in System class , it is placed in System class only .

[@nicholascousar4306]

Is that what is meant by "out" being listed as a field, rather than a subclass of the System class?

[@valdemirmaximo5064]

Hi, I'm trying to use this method in Netbeans, but I can't find the place to enter the character and type enter. In the output it doesn't work. Do you have any idea?

[@VC.Vishal]

ASCII code for Enter is 13. while(i!=13) { i=System.in.read(); str = str + (char)i; }

[@vishnukiran3847]

ASCII code for Enter key is 10. 13 is for Carriage return key.

[@divyeshkumarbalar7732]

@@vishnukiran3847 That is what happens when you enter

[@divyeshkumarbalar7732]

but nevermind, both works equally

[@nilaythakkar]

Really Helpful.Thank You so much

[@bilehchoudhury3432]

Why is this program not wait for String input import java.util.*; class Input{ public static void main(String args[]) { Scanner s=new Scanner(System.in); System.out.println("Enter Age"); int x=s.nextInt(); System.out.println("Enter Your name "); String name=s.nextLine(); System.out.println("Name is : "+name+"Age is :"+x); } }

[@manujkumarjoshi9342]

since you are having some code upward, your Navin reddy code is conflicting with that. Else it is working fine.

[@kirangadhave8152]

ASCII value for Enter is 10 i think. It didnt display the ASCII value for ENTER because you typecast i as char in sout statement. I think! Awesome tutorial series btw!

[@souvikpal6262]

9.4 is missing .. Please post the link in playlist.

[@the_laptopgamer7167]

kzbin.info/www/bejne/oGXUqH6VbZqefbc found this on youtube .. and I believe this one is the missing part of bufferedreader ... But I have no idea how someone else is uploading it on youtube while the owner of this video is missing it from his playlist

[@souvikpal6262]

Omg ! Yes .

[@alokdubey4771]

Sir we can write this also na While(system.in.read()!='\0') Sir please try this also I don't have a system in my house that's why I'm telling you

[@dr.nishachaudhary5895]

yes we can. but you cannot.....as you dont have a system, so first take a system, then right the code you suggested.... it will work ....ha ha ha

[@aarushigupta1106]

sir commenting for marker interface is disabled so my question is on marker interface can u quote an example for its use if we know that we have implemented P then why we need to check

[@LogicalManSujeet]

what is your paid course

[@xyber_punk]

public class UserInput { public static void main(String[] args) throws Exception { int i=System.in.read(); System.out.print((char)i); String str=""; while((i=System.in.read())!=10) str=str+(char)i; System.out.println(str); } }

[@mohammedviso2269]

Nice

[@WorldWorrier3273]

I think you are also a beginner in Java.

[@mitashasrivastava9605]

when I am taking an string input using this method Dan it is going to infinite loop.can uh plss help?

[@vandachhoeung1976]

I like it

[@WorldWorrier3273]

I think you aren't comfortable with Java , and you shows a lots of add too which is really makes us unhappy ☹️
