[@shahdhardik]

Your videos are good . One suggestions is that in your videos show font are too small . would be great to have those bigger readable fonts. But i really appreciate the learning i get from videos.

[@tommyjason5035]

Same issue faced by me as well

[@akulabhaskar3797]

Naveeen u r just amazing

[@lucylucy8517]

Best explanation sir...

[@jahangiralikhan2410]

Hi Naveen, Can you please make a video where we use in real projects in automation testing. it would be very helpful for the automation community who watches the video.
A humble request from my side
Thanks! :)

[@devjewel8345]

It's been a great journey up to here ...

[@mudaseerahmed7336]

Nice

[@thiery572]

Oooo.... :)

[@itindranil]

Example of String to Char
String j = "Ant";
char c = j.charAt(0); //charAt() method will convert first index of string to char
System.out.println(c); // will print A
char[] c_Array = j.toCharArray(); // returns a length 3 char array ['A','n','t']
System.out.println(c_Array);

[@sriranganathtottadi2102]

Arrays.toString(c_Array) will print ['A','n','t']. here just an fyi

[@spidyniks]

Naveen nice and clearly explained. But why these classes are named wrapper claases?

[@sumayazamasyed8982]

Hi Naveen sir, I've a doubt... please tell me how run () method of thread class is user defined in Java? ... Thread class consists of all these methods like start () getState() etc these are built in but run () is user defined how is it possible? Thanks

[@ravurisandeep8377]

Who told u run() is user-defined..it is predefined method signature

[@VaishnavM.Wakale]

Hi Naveen, Did you share all the code anywhere?

[@timetogrow1306]

Can u complete the Java series

[@shrijayantjain4837]

Can't we convert string into character, like other datatypes ?

[@pvenugopalarao9066]

//conversion from String to Chars
String s="AnyString";
char[] chars = s.toCharArray();
for(char temp:chars) {
System.out.println(temp);
}

[@RahulJha-bu7cv]

//String to Char
String q = "ABC";
char a = q.charAt(0);
char b = q.charAt(1);
char c = q.charAt(2);
System.out.println(a);
System.out.println(b);
System.out.println(c);
//OR
String S = "HELLO";
char arrchar[] = S.toCharArray();
for(int i=0; i

[@amangiri6429]

thanks man

[@rupaguzar6589]

is instance variable and global variable is same

[@damuappanna4188]

Instance variable and global variable both are different. Instance variables also called as non static variables where as global variable can be declared with static keyword
