public class Main { public static void main(String[] args) { for (int i = 1; i <= 100; i++) { if (i % 3 == 0 && i % 5 == 0) { System.out.println(i + " is a tech number"); } } } }This program uses a for loop to iterate through the numbers 1 to 100. For each number, it checks if the number is divisible by both 3 and 5. If it is, then it prints the number as a tech number.
