Great work, you're helping me preparing for the exam

String a="hello" final Integer i=10; S.o.Pln(a+i) ---hello10 it will print. it wont give any error

Nice Video Thanks This can be a continuous series 👍

Great Video. One correction. ArrayList list = new ArrayList(); // This does not throw any Compilation Error.

So nice of you

Good content Just keep in mind the following stuff when it comes to lists with generic types , because i saw/heard you describe something wrong. ArrayList list = new ArrayList(); //This works and without generic determination it allows you to save a String, a Person or any other object ArrayList list = new ArrayList(); //This works as well and it will allow you to save only Strings ArrayList list = new ArrayList(); //This works like the previous one and only saves Strings, but is the correct way of declaring a list

Very good for last minute quick look of java concept.

Awesome content!

You are the gem i was looking for. If all these needs to be self realised by seeing all examples and outputs takes immense time which you made so easy for last minute exam rush preparation. But whoever correcting or asking doubts please explain or correct in one comment and pin that. Thank you so much for the video 😇.

Hi, Thanks for the video. It is really helpful. Few corrections I would like to add: Corrrection 1: at time 6:00 minutte, you said println will not take void and there is compilation error. This is not correct. Println method can take void ( System.out.println() -> this works fine, does not throw compile time error , prints nothing and adds a new line , if you print another println you will see). where as print method can not take void ( System.out.print()->compilation error). Note : passing void keyword ( or passing any keywords like passing int/float/char or String ) to print() or println() will anyway gives compilation error. example : print(int) / print(String) / Println(void) -> all provides compilation error. Correction 2: String a="hello" final Integer i=10; S.o.P(a+i) ---> hello10 will be printed, no compilation error Correction 3 : ArrayList list = new ArrayList(); // This does not throw any Compilation Error. Thanks again for making these videos. Really appreciate your efforts.

14:45, b[0] b[1] will be null beacuse, it is wrapper class. default value of boolean is false. array of object of any wrapper class will always be null. eg. Integer a[] = new Integer[3]; // will default null int a[] = new int[3]; // will default 0 boolean b[] = new boolean[3]; // will default false Boolean b[] = new Boolean[3]; // will default null

Hi anyone knows how the question format will be like in the real exam? Would the questions have like subtopics of what we are going to be tested on?

did you test: final Integer i=10; String a="hellow"; Systeme.out.println(a+i)? It should be hello10 but you said it will result error.

Part 2 please !!

I have uploaded part 2 plz check

hi, good work. Thanks for sharing your knowledge. in 10:05, mentioned that all Wrapper Classes extends Number, which is not 100% true. Boolean and Character are derived directly from Object class.

You seems wrong on 14:10 ... String s = " like "; Integer i = 6; System.out.println(s+i); Output is : like 6

But System.out.println(s.concat(i)); This will throw compile issue.... To resolve that use.. : i.toString()

Hi Wrapper + concatination work for me Integer a = 10; System.out.println("--"+a); Can u clarify it to me

Notes will be published soon

boolean b[] = new boolean [5]; b[0] will print false

info for minutes 16 -> int[] numbers = new int[10]; Integer[] numbers2 = new Integer[10]; long[] numbers3 = new long[10]; boolean[] booleans = new boolean[8]; Boolean[] booleans2 = new Boolean[8]; System.out.println(numbers[2]); // default value 0 for primitive numbers System.out.println(numbers2[5]); // default value null for objects System.out.println(numbers3[4]); // default value 0 for primitive numbers System.out.println(booleans[4]); // default value false for primitive boolean System.out.println(booleans2[4]); // default value null for objects
