Java Programming Tutorial 10 – Scanner Input

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

didnt really help me at all… 🙁

Built this little program using the lesson and the comments! I'm so excited!
import java.util.Scanner;
public class MySweetProgram {
public static void main(String[] args) {
System.out.println("What is your birthyear? Imma guess your age");
Scanner scanner = new Scanner(System.in);
int x = 2020;
int y = scanner.nextInt();
int a = x – y;
int a1 = a + 1;
int a2 = a – 1;
System.out.println(a);
System.out.println("Hell yeah, I knew you were " + a + " years old");
boolean age = scanner.nextBoolean();
if (age) {
System.out.println("That's what I'm talking about");
}
else {
System.out.println("Oh shit! So you're probably " + a1 + " years old!");

}

boolean age2 = scanner.nextBoolean();
if (age) {
System.out.println("Alriiiiiight");
}
else {
System.out.println("Oh damn…wait, so you're " + a2 + " years old!");

}

boolean age3 = scanner.nextBoolean();
if (age) {
System.out.println("Yeah, I mean, what other choices are there?");
}
else {
System.out.println("Dafaq? Man cut that bullshit, I'm done");

}
}
}

i am using repl.it

meh… what about scanner.close() and going further?

So like
Scanner scanner = new Scanner(sysin);
…do something
scanner.close();

… later

scanner = new Scanner(sysin); <– same var name.
object.setName(scanner.next());
scanner.close();

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.

It's not repeating what I type. Help?

Thanks a ton for this!!! <3

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

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???

Fast pace on casting

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

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

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

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

you are a good teacher. thnx

how is y assigned to 20?
