  Program that prints out repetitives of 3,5 and both of them

public static void main(String args[]) {

       for(int i = 1; i &lt; 101; i++)
       {
           if(i%3 == 0)
           {
           System.out.println("repetitive of 3");
           }

           else if(i%5 == 0)
           {
           System.out.println("repetitive of 5");
           }

           else if(i%5 == 0 &amp;&amp; i%3 == 0)
           {
           System.out.println("repetitive of 3 and 5");
           }
           else{
               System.out.println(i);
           }
       }
   }
}



First of please format your code properly as it helps to read it. I've formatted the code as it is suggested for java:

public static void main(String args[]) {
    for (int i = 1; i &lt; 101; i++) {
        if (i%3 == 0) {
            System.out.println("repetitive of 3");
        } else if (i%5 == 0) {
            System.out.println("repetitive of 5");
        } else if (i%5 == 0 &amp;&amp; i%3 == 0) {
            System.out.println("repetitive of 3 and 5");
        } else {
            System.out.println(i);
        }
    }
}


Now for the review:

The third if will never be reached as the first if already matches.

So to get the result wanted you have to change the first and third if branch:

public static void main(String args[]) {
    for (int i = 1; i &lt; 101; i++) {
        if (i%5 == 0 &amp;&amp; i%3 == 0) {
            System.out.println("repetitive of 3 and 5");
        } else if (i%5 == 0) {
            System.out.println("repetitive of 5");
        } else if (i%3 == 0) {
            System.out.println("repetitive of 3");
        } else {
            System.out.println(i);
        }
    }
}


Using the method main() for small tests is fine but it is better to create objects and use them from the beginning.

Else the program look good so far.
