and Python ?

Do you have "Taco Queen" as a hotkey? .....do i want to know why?

[@renejacques8288]

Every video and textbook has told me not to used float or double for money, but they never told me what to use. That was my biggest question. I've been around java now for 22 years now off and on, and this is the very first time I'm told what data type to use for currency. Thanks.

This has helped me a lot! I was able to make a program that guesses your age based off of your birth year input!

[@jebskie7661]

{ Int currentyear = 2019 Int birthyear = 0 Int result = 0 He will then input his birthyear Int result = currentyear - birthyear System.out.println("This is your age:" - result); }

[@jebskie7661]

Is mine correct?

[@been5703]

@@jebskie7661 That didnt work for me. What is the purpose of int result = 0?

[@been5703]

@@jebskie7661 { System.out.println("What year were you born?"); Scanner scanner = new Scanner(System.in); int currentyear = 2019; int birthyear = scanner.nextInt(); //He will then input his birthyear int result1 = currentyear - birthyear; System.out.println("This is your age: " + result1); }

[@chirupower1317]

System.out.println("enter your dob year"); Scanner scan = new Scanner(System.in); int year = scan.nextInt(); int age = 2019 - year ; System.out.println("you are " + age + "years old");

[@HyperActive94]

you are a good teacher. thnx

[@flameofthephoenix8395]

2:51 It's interesting to think about how this is a program taking input, outputting that input, and then using the input for a secondary program which also outputs the input.

Thank you for the wonderful videos! They serve as a good alternative for when book learning gets a bit boring. :)

word to my mother this guy better than all my lecturers lmao

[@JoshuaTCoe]

look at curry man, so inspirational

[@meghasbabu3437]

Thanks a ton for this!!!

[@OccupyZero2One]

Spot on with the explanation!!

[@ballerinamoon]

Your videos are so enjoyable.. Are you that New Boston guy?

[@tishaanants]

Thanks

[@karmac2023]

explanations are great! thank you

[@facemonster114]

Great video again man

[@hawadrammeh8870]

Thank you

[@kirsher1356]

what are you using to enter the code?

[@matwit91]

Thank you for your video, I have one question about an Eclipse. On 4th minute you are showing some windows with tips, on my version is all dark. How is called that? Maybe I will find it, or if you know how can I change it? Same issue with dark or light appearance - it's always black like blank page.

[@matwit91]

I found name of it. It's called Javadoc

[@elhombreenmascarado5640]

Mister, if using encapsulation, when having a class with its private attributes, I only need to enter data using the set method. How do I implement Scanner in the set method for classes with private attributes?

[@miminiz3268]

is scanner the equivalent to cin in c++?

[@Harda1337]

Is there a scanner type for "char" or do I use byte in that case?

[@Harda1337]

Nevermind I found out that you can use next().charAt(0) to read which character the first character in the string was.

[@dopeydoggo775]

At around 5:20 I don't get an input mismatch error if I just put in a random letter or number to the boolean scanner, it just evaluates as false

[@samedsgrtmc4787]

it is confusing to name the variable as scanner, not a good choice for new learners.

[@j3froc63]

At 2:42 line 9: int y=scanner.nextInt(), what if I wrote in the console log "abc123"??? Does it find the next Int and store it in variable y???

[@Rose-Stro]

my code won't even run. When I input string x = scan.nextLine(); or even string x = scan.next(); , the code after it won't even run.

[@paxthewax4203]

what IDE are yo using?

[@ebrahiemryklief8855]

Do you clear the previous lines of code before you start a new line?

[@Babbelmus]

meh... what about scanner.close() and going further? So like Scanner scanner = new Scanner(sysin); ...do something scanner.close(); ... later scanner = new Scanner(sysin);

[@Cookingcousin]

Hey, can someone explain the importance of scanner before a method?

[@kakoliparial4410]

The Scanner Input Tutorial 10 was not very clear.

[@vivianamullen2527]

It's not repeating what I type. Help?

[@haseebmalik2983]

i get it now never mind

[@ashprasad9075]

How did you get ?

i am using repl.it

[@darrylalexanderevanswebgra4897]

Thanks. I have another question to ask you about a problem. Can I send you a screen shot?

[@haseebmalik2983]

i want a scanner that asks a question to the user. He then puts in a value then it gives the value. exp: enter number of students applied to college enter how many get accpeted; then the value it gives is the the acceptance rate in percentage. help please

[@clararoads4854]

Scanner scanner = new Scanner(System.in); /* * a scanner is unable to "ask a question to the user", to print a message to * the console, "System.out.println()" must be used */ float applied = 0f; float accepted = 0f; System.out.println("enter number of students applied to college"); String appliedString = scanner.nextLine(); // the input must be taken in String format, then converted to int, per the try-catch block try { applied = Integer.parseInt(appliedString); } catch (NumberFormatException e) { System.exit(1); } System.out.println("enter number of students to get accepted to college"); String acceptedString = scanner.nextLine(); try { accepted = Integer.parseInt(acceptedString); } catch (NumberFormatException e) { System.exit(1); } float acceptanceRate = (accepted / applied)* 100; System.out.println("the acceptance percentage is : " + acceptanceRate + "%");
