Multiple choice

What will be the output of the program? class Equals { public static void main(String [] args) { int x = 100; double y = 100.1; boolean b = (x = y); /* Line 7 */ System.out.println(b); } }

  1. true

  2. false

  3. Compilation fails

  4. An exception is thrown at runtime
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The code will not compile because in line 7, the line will work only if we use (x==y) in the line. The == operator compares values to produce a boolean, whereas the = operator assigns a value to variables. Option A, B, and D are incorrect because the code does not get as far as compiling. If we corrected this code, the output would be false.
