Be keeping an eye out for this

I would like smaller and easier tutorials like constructor tutorial you made that was pretty good

In chapter 8 I was taught something called casting (not working with the scanner class). Are both what I mentioned and what you tought us equaly valid or is there a difference?

At 6:36, how did you delete the whole line so quickly without selecting the characters ? What is that keyboard shortcut ?

i have a question at around 11:05, I saw you assigned floatAge the value inside of the try block, but declared it outside of it. Is this necessary, or could you declare floatAge and initialize both inside of the try block?

I can't make a cheese sandwich into a float, but I can make ice cream into a float by pouring soda on it.

How to make the scanner inputs are beside the question??

Can you explain why you can’t reopen a Scanner after you call close?

Hi John. I have a strange issue. I expect code below to allow me to enter 3 string elements from keyboard but unfortunately after entering two strings, immediately I see the output of myStrings array which looks odd: [FirstString, , SecondString]. There is an empty element between myStrings[0] and myStrings[2]? Why? It is expecting that each scanner.nextLine() will consume the new line including \n; but the situation is not as such?

import java.util.Arrays;
import java.util.Scanner;

public class Main {
private static Scanner scanner = new Scanner(System.in);

public static void main(String[] args) {
String[] myStrings = getStrings(3);

}

public static String[] getStrings(int number){
System.out.println("Enter "+number+" strings\r");
String[] values = new String[number];
for (int i=0;i< values.length;i++){
values[i]=scanner.nextLine();
}
return values;
}
}

Great video, but can I have a question ? Why my scanner nextFloat read float from keyboard with comma instead of dot ?, can you help me . Thanks

[Pacvalham]

I prefer a bang instead of "== false".
