Given: 

class TKO {
    public static void main(String[] args) {
        String s = "-";
        Integer x = 343;
        long L343 = 343L;
        if(x.equals(L343))  s += ".e1 ";
        if(x.equals(343))  s += ".e2 ";
        Short s1 = (short)((new Short((short)343)) / (new Short((short)49)));
        if(s1 == 7)        s += "=s ";
        if(s1 < new Integer(7+1))  s += "fly ";
        System.out.println(s);
    }
}

Correct Option: B,C,D

AI Explanation

To determine which options will be included in the output String s, let's analyze the given code step by step:

  1. String s = "-"; - Initialize the String s with a hyphen.

  2. Integer x = 343; - Declare and initialize an Integer variable x with the value 343.

  3. long L343 = 343L; - Declare and initialize a long variable L343 with the value 343L.

  4. if(x.equals(L343)) s += ".e1 "; - This condition checks if the value of x is equal to the value of L343. Since x is an Integer object and L343 is a long, the condition evaluates to false. Therefore, ".e1" is not included in s.

  5. if(x.equals(343)) s += ".e2 "; - This condition checks if the value of x is equal to the value 343. Since x is an Integer object and 343 is an int, the condition evaluates to true. Therefore, ".e2" is included in s.

  6. Short s1 = (short)((new Short((short)343)) / (new Short((short)49))); - Declare and initialize a Short variable s1 by dividing two Short objects, both initialized with the value 343 and 49 respectively. The division result is 7.

  7. if(s1 == 7) s += "=s "; - This condition checks if the value of s1 is equal to 7. Since s1 is equal to 7, the condition evaluates to true. Therefore, "=s" is included in s.

  8. if(s1 < new Integer(7+1)) s += "fly "; - This condition checks if the value of s1 is less than (7+1), which is 8. Since s1 is less than 8, the condition evaluates to true. Therefore, "fly" is included in s.

  9. System.out.println(s); - Print the value of s, which consists of ".e2 =s fly".

Based on the analysis above, the options that will be included in the output String s are:

B. .e2 C. =s D. fly

Therefore, the correct answer is B, C, D.
