8:08 As I am from python lang. , I knew that strings can be separated inside the print statement by commas(,), but in JAVA now I came to know that + is to be given to separate two strings in the print statement. Thanks a lot for it , btw as I got error in that separation of strings I tried a new method which I want to share. System.out.print("Enter your name:"); String str1 = S.next(); System.out.print("Hello,"); System.out.print(str1); System.out.print(" Have a nice day"); Thought of making in the same line which is required in the output , which can be done by just removing ln from print statement, so I did like that. I hope if anyone is seeing can understand it along with it's essence. Thanks a lot Harry .❤❤
Thanks bro, I came from C++ background and I have been trying to use , to separate a string and a pre defined literal. 😂 But it never worked. Today I knew we have to use + 😅❤
9:13 I did the same using different method , took a bool value and then checked it. Anyways , directly putting the condition in the print statement is also not bad. My answer:- System.out.println("Enter an integer:"); boolean b= S.hasNextInt(); System.out.println(b); Thanks a lot , Harry.

Hello harry bhai ... I'm a government employee in municipal corporation jaipur ... I'm want to tell you that how i found you ... Ek bar me MLA election duty me gaya tha wha mujhe ek banda mila usne mujhe pucha ki kya krte ho study me kya interest h to mene use bataya ki mujhe programming language padhni he jo mere liye hacking me bahit kam aayegi to usne bataya ki RU-vid pr ek channel h code with harry naam se ek bar check krna ....harry bhai tb se me aapke videos dekh rha hu or apki playlist bhi access kr rkhta hu ...you are one of my favorite ❤️
I am watching your java video just before a month .it's awesome👍👍😊😊😊 for understanding from beginners level to higher level... and I also finish half century play list both java&html-css-javascript
8:30 Float can't be used here . As the mile conversion unit is a long decimal , so Double is to used here for our convenience. I did float input in Km to m, but it came as error in conversion of Km to miles , so I came to know of my another mistake here. System.out.println("Enter Distance in Kilometers:"); double a=S.nextDouble() ; double b = a*0.621371; System.out.println("Distance in miles is:"); System.out.println(b); Got the correct answer now. Thanks a lot, Harry brother Edit : float can also be done
4:17 Yes , float/double should be used . I did the same mistake when I was solving the question of last challenge (5 subjects CGPA). I then thought of the decimal answer and then converted each input into float data type. IDK why you are not taking user input process but that is the actual process which everyone should follow , although by taking direct input it will be easy for the beginners. P.S. :- I am basically used to python so there float or int , data type doesn't matter, so I generally thought if taking data input as int from the user which is wrong. Thanks .❤❤
Can you help me? I took input in integer and I made two variables which hold value total marks of exam and total marks obtained, then I made an integer variable to calculate percentage but when I am using int, it is showing zero everytime but when I use float then the same exact program is working, why and how? I input marks according to that it make 90 percent but it works in float but not in int 😢
System.out.println("how many number of kilometers you want to convert in miles"); Scanner s = new Scanner(System.in); double kilometers = s.nextDouble(); System.out.println("MILES =" + kilometers* 0.621); this is how i did my code . The value of miles is approximate
Since 1 km = 0.621 , we see some decimal numbers here, by which we understood that we are going to deal with decimals in this code. So the data type related to decimals can be float or double. Tip = when finding CGPA or percentage, we know we are gonna get our answer in decimals, so for such type of questions we always use float or double.
Sir actually I am learning java from your video in 2021 and I had seen all the lectures and I had solve the problem which asked in lecture 5 by my own kindly look into it and correct it if l had done any error in it
double km = 1; double miles = 0.621371; System.out.println("Enter kilometers"); Scanner sc = new Scanner(System.in); double kms = sc.nextDouble(); double output = kms*miles; System.out.println(output); } } It took all my brain power so i suggest revision after every letcure is must. Happy Programming😄
8:26 OMG F . I had done this one as Km to m day before yesterday while practice. Going to try now. THIS IS WHY QUESTION READING SHOULD BE DONE THOROUGHLY. Sorry to myself as well as to Harry for not reading the question correctly, although I have applied the same concept there which is to be done. Going to change it now. Will come and share the answer.
2:20 But the same can be done by taking user input . You had did the same thing while telling us about data types but it was acceptable then as we had not learnt about the user input. But as we know we should take user input (user's choice of integers), and then run the program.
