i am making a program to see if a number is divisible by 5 and/or 6. how do i do this using a boolean? the user inputs and int and then i calculate it and tell them true and/or false. thanks

i am making a program to see if a number is divisible by 5 and/or 6. how do i do this using a boolean? the user inputs and int and then i calculate it and tell them true and/or false. thanks
Which part of this is giving you trouble? Determining divisibility? Storing something in a variable? Using a boolean variable? Outputting a variable?
well actually it doesnt have to be boolean i realized. I have no idea how to see if a number is divisible by another, so help needed there. But as for the data type i just need one that states true if it is divisible and false if it isnt. please help. thanks
heres what i have so far... dont have the divisibility equation yet.
Code java:
import java.util.Scanner; public class Pg127 { public static void main(String[] args) { //Input and output= Console Scanner input= new Scanner(System.in); System.out.println("Enter an interger: "); String number=input.next(); int integer = Integer.parseInt(number); if( integer 5 && integer 6){ System.out.println("Is " + integer + " divisible by 5 and 6? "); } else if(integer 5 || integer 6){ System.out.println("Is " + integer + " divisible by 5 or 6? "); } else if (integer 5 || integer 6 ){ System.out.println("Is " + integer + " divisible by 5 and 6, but not both? "); } } }
also on the last one i have to make it ask if it is divisible by one or the other but not both... i know i have to add an && but how do i specify NOT
nevermind, i actually ended up figuring it out.
Heres what I ended with:
Code java:
import java.util.Scanner; public class Pg127 { public static void main(String[] args) { //Input and output= Console Scanner input = new Scanner(System.in); System.out.println("Enter an interger: "); String number = input.next(); int integer = Integer.parseInt(number); if (integer % 5 == 0 && integer % 6 == 0) { System.out.println("Is " + integer + " divisible by 5 and 6? True"); } else { System.out.println("Is " + integer + " divisible by 5 and 6? False"); } if (integer % 5 == 0 || integer % 6 == 0) { System.out.println("Is " + integer + " divisible by 5 or 6? True "); } else { System.out.println("Is " + integer + " divisible by 5 or 6? False"); } if (integer % 5 == 0 && integer % 6 == 0) { System.out.println("Is " + integer + " divisible by 5 and 6, but not both? False "); } else { System.out.println("Is " + integer + " divisible by 5 or 6, but not both? True "); } } }
Thank you so much for responding though. I was just not using my brain earlier and made it harder than it should have been haha.
It still appears more complicated than is necessary in my opinion.
For example I see:
integer % 5 == 0
and:
integer % 6 == 0
each three times in your code. This means you are doing the same work three times.
When I think of your problem, I see a solution in my head formed in the following layout:
program starts
user enters (valid) input
determine if input % 5 == 0
determine if input % 6 == 0
combine the results into a formatted output
display results
