Question

What output is produced by the following code? Integer first = new Integer(7); Integer second = first; if (first == second) System.out.println("Sneezy"); else System.out.println("Grumpy"); if (first.equals(second)) System.out.println("Sleepy"); else System.out.println("Doc"); Sneezy Sleepy Sneezy Doc Grumpy Sleepy Grumpy Doc

Answer 1

Answer:

The correct output of this question is  "Sneezy Sleepy".

Explanation:

In the given code firstly we create the object of the integer class that is first in this we pass the integer value that is 7. Then we declare another second integer variable is this variable we pass object as a reference. Then we use the two conditional statements. In the first, if block we check that the object of the class is equal to the reference variable. If it is true it prints Sneezy. otherwise, it will print Grumpy. In second if block we check that the object of the class is equal to the reference variable. but in this time we the equals() function it is the same as(==). If the condition is true it prints Sleepy. otherwise, it will print Doc. So the output of the code is Sneezy Sleepy.
