Answer:

     if(isEmpty || numOfCredits==3){

         

     }

Explanation:

Consider a complete java program below that prompts user for  number of credits and also asks if class roster is empty or not

<em>import java.util.Scanner;</em>

<em>public class num13 {</em>

<em>    public static void main(String[] args) {</em>

<em>        boolean isEmpty = false;</em>

<em>        Scanner in = new Scanner(System.in);</em>

<em>        System.out.println("Is class Rooster Empty? Yes or No");</em>

<em>        String ans = in.next();</em>

<em>        if(ans.equalsIgnoreCase("yes")){</em>

<em>            isEmpty = true;</em>

<em>        }</em>

<em>        else isEmpty =false;</em>

<em>        System.out.println("Enter number of credits");</em>

<em>      int numOfCredits = in.nextInt();</em>

<em>      if(isEmpty||numOfCredits==3){</em>

<em>          System.out.println("True");</em>

<em>      }</em>

<em>      else {</em>

<em>          System.out.println("Not true");</em>

<em>      }</em>

<em>    }</em>

<em>}</em>
