I have purchased 2 courses to understand Selenium and Java and i spent almost 13k rupees, they didn't tell me so elaborately even after charging so much. your tutorials are really helpful, one can easily understand and learn, moreover they can get enough confidence in few days to crack any MNC interview. Great job Naveen. Keep it up. please keep these tutorials free in future as well.

[shilpathada]

String str = "The rains have started here selenium";
System.out.println(str.indexOf(('s'), str.indexOf('s') + str.indexOf('s')+1));//3rd occurrence of 's'

[deepikavijay]

Hi Naveen. Nice video. Could you please prepare a video for Regex ?

[ParthKandpal]

Hi Naveen,
Please find below the code for 3rd occurence of s

String str="The Rains have started here selenium";


System.out.println(str.indexOf("s",


output will be -->28

I'm not able to print 3rd occurance of 's'...I did this System.out.println(s.indexOf('s', s.indexOf('s', s.indexOf('s')+1))); ...

[Ruchi]

Thanks a lot !
Please do a few programs on Collections...

[kalyanitarawate]

The letters are not clearly visible. Explanation is good.

[navathutejomai]

Sir I got a doubt as string is immutable how can we concatenate and assign to same string, just read on net that a new string is created and it reference is set to the object reference.

[khushbooshah]

one doubt Output2.IndexOf("W", Output2.IndexOf("W")+1) how will i get the index of 3rd occruence of W in string

[Testprofile-ub]

Using new keyword creates memory in heap and SCP . Why is that soo?

[aakashkhandekar]

PLEASE MAKE VIDEOS ON ZOOM MODE. I AM NOT ABLE TO SEE YOUR CODES PROPERLY...

[nazimkhan]

Lets take this example
String s="_Hello_world_";
String test[]=s.split("_");
Return 3: Why?

[devarapallirohini]

Hi Naveen, i am unable to print the 3rd occurance in the sentence, tried it in many ways. Google is having some complex code.
Could you please provide your inputs.
