All my interest in Java is because of you. I can't thank you enough for all that you have done for us!! 👏

[praveen]

Thanks Naveen for the video . For the assessment we just have to remove not symbol from if(String.valueOf(c).is blank()).

[surabhibn]

Your approach is really so easy to understand and you solve the program in most efficient way too
Thank you so much...

[shashikumarkondoju]

Thankyou sir the way you explained awesome..it's makes every one to easy understand...
For only spaces count we use instead of not if condition

[lavanya.ds]

Thank you souch for sharing this Naveen, this is mandatory question asked in many interviews for experienced candidates

[antarabanerjee]

Thanks for the explanation Naveen. It's because of you, yesterday I cracked one more interview!

[anilds]

solution for counting space
int count=0;
for(char ch:name.toCharArray()) {
if(ch==' ') {
count++;
}
}

System.out.println(count);

Hi NAVEEN,
Good day!

The same program I was facing in the technical round and I wrote and explained to the interviewer. I cracked and cleared the first round as well. Thank you, please post more mock interviews. Thanks a lot..

For checking space, replace "a" with space : String str = "this is a java programming";
int result = str.length()- str.replaceAll("a", "").length();
System.out.println(result);

[thatsdeep]

YOU'RE THE MAN!!, THANK but why u had to test ur code for 10 min lol

[anilds]

Solution for only space we need to take count of string and replaceall method
int ", "").length();

System.out.println(n);

[ashuiet]

most of the interview this question asked ...if not this then ...some what similar to this problem.

[khajazakiuddin]

Thank you so much for the amazing videos on Java concepts Naveen. it really helps in improving my coding skills. Could you also please make a video on how to print all the permutations of a given string "abc" (like acb, bca, cab, cba..etc., ). (It was asked in the interview with ADP company). There are many logics present on the internet but not fully understandable, just wanted to get it from you which obviously would be easy to understand and implement.

[ParamjitKaur-josz]

To count only spaces, we will remove NOT from condition like below

[Wandereatstravel]

Print occurences of each word and character in a string : it was asked in the interview

[programminghubbharat]

Yes sir, by just removing the (!) In the
we got only spaces

[aparna]

This program is case sensitive
the uppercase and lowercase occurences of same letters are counted seperately.

[MrAshu]

I am well versed in Python, Should I learn Java as well?

[lathaa]

Make a video for String Builder and String Buffer bro.

[devanandthirunavukkarasu]

sir. thanks for the video .can we do this in java 8
