It rained heavily today and I decided to go to work later without a car. Look at the code first:public static void Main (string[] args) { Integer a=1000,b=1000; Integer c=100,d=100; System.out.println (a==b); System.out.println (C==d); }Think about your Java knowledge, what is the output?Post the answer, run the code and we'll get false true. We know that = = comparison is a reference to two objects, where ABCD is the newly created object, supposedly should be output false. This i
