I need help with the Java logical and OR challenge I can't figure it out

Answer 1

To check if an integer is a multiple of another integer you can use the modulo operator %. If the remainder is 0 then it is a multiple of that number.
Example: to check if a number is a multiple of 10 use;
num % 10 == 0
So if you wanted to check if a number was a multiple of both 10 AND 9 (i.e. 90, 180, 900, etc), and then run some code if true you could do;

if (num % 10 == 0 && num % 9 == 0) {
... code to run if true ...
}

For either 4 OR 6;

if (num % 4 == 0 || num % 6 == 0) {
... code to run if true ...
}

Answer 2

num is a variable in my examples, so you just store the number input by the user in a variable making sure you converted it to the correct type. nextInt()

Answer 3

The source of the number is irrelevant, the code ChaoticDawg notes above works for a number no matter it's source.

Answer 4

#Dan Carney:
else {System.out.println("Try again");}
I hope will be work.

Answer 5

struggling with this one. it passes tests 1-4 but not the 5th one. any sense on what im doing wrong here?

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner read = new Scanner(System.in);
int ticketNumber = read.nextInt();
int zero = 0;

if (ticketNumber%9 == zero && ticketNumber%10 == zero) {System.out.println("You won $200");}

else if (ticketNumber%4 == zero || ticketNumber%6 == zero){System.out.println("You won $50");}

else {System.out.println("Please try again");}

}

}

Answer 6

Yes I am suppose to create a program were I use both to decided on a winners of lottery tickets

It's not so that don't know how to use the logical and OR
It the fact that the winner have to be decided based on a multi of a number
Like if the ticket number
Is equal to a multiple of 10 and 9 they win the first prize
Or they have ether a multiple of 4 or 6

That's what throws me of

Answer 7

Hello Chaotic Dawg thank you it worked

Answer 8

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner read = new Scanner(System.in);
int num = read.nextInt();
int z = 0;

//your code goes here

//Hint: Number a is a multiple of number b, if a%b

//If the ticket number is a multiple of 10 and 9, the program outputs “You won $200”.
if(num%10 == z && num%9 == z)
{System.out.println("You won $200");}

//If it is a multiple of 4 or 6, the program outputs “You won $50”.
else if(num%4 == z || num%6 == z)
{System.out.println("You won $50");}

//Otherwise, there is no prize and the output is “Try again”.
else { System.out.println("Try again");}

}
}
//FZ

// I hope you guys can understand my code

Answer 9

And what if the number comes from a user input

Answer 10

Yes I did see
Once again thanks

And there any other practice test you have I be

Answer 11

Glad to try it out
