Question

W.A.P to display a number which are not divisible by 3 and 7 between 1 to 100 in JAVA​

Answer 1

Answer:

If you mean display number not divisibly by both 3 and 7 (as in 21, 42 and so one)

The program:

$\\\tt public\ class\ oh\ \{ public\ static\ void\ main(String[] args) \{ for\ (int\ i = 1; i <101; i++) \{ if (i \%3!=0 || i \%7!=0) \{ System.out.print(i+" " ); \} \}\}$

If you mean display number not divisibly by neither 3 or 7 (as in 3,6,7,9,12,14 and so one)

The program:

$\\\tt public\ class\ oh\ \{ public\ static\ void\ main(String[] args) \{ for\ (int\ i = 1; i < 101; i++) \{ if (i \%3!=0 \&\& i \%7!=0) \{ System.out.print(i+" " ); \} \}\}$

Explanation:

1. i%7!=0 && i%3!=0 will check if the number if the number is divisible by 7 and 3 or not and the print the number with System.out.print()
2. similarly i%7!=0 || i%3!=0 will check if the number is either 7 or 3.

Answer 2

Question:-

• To Display those numbers which are not divisible by 3 and 7 between 1 to 100

Code Language:-

• Java

_______________________

Code:-

package Coder;

public class DivCheck

{

public static void main (String ar [])

{

System.out.println("The numbers not divisible by 3 and 7 are:");

for(i=1;i<=100;i++)

{

if(i%3!=0)&&(i%7!=0)

System.out.println(i);

}

}

}

__________________________

Code Explaination:-

1. The program runs a loop from 1 to 100
2. In each iteration, it checks if the loop value is divisible by 3 and 7 or not.
3. If not divisible, it displays the number
4. Else it will continue with next iteration
