Answer:
Hi there! The question is quizzing on your knowledge of type casting. Please find the explanation below.
Explanation:
The first program declares a Test class containing the main function in which two objects of class A are created and compared. The main function is the entry point of a Java program. After objects a1 and a2 are created, their comparison function “equals” is invoked and the result printed on the screen with the “System.out.println” method. The second program is the same in this respect, except for the implementation of class A. In the first program, class A has the property “x” defined as an int. The method “equals” accepts any object and type casts (converts) the passed object to a type of class A and compares and returns whether the property x of the type-casted object matches the property of the current object a. In the second program, the equals method of class A only accepts an input parameter of class A and returns whether the property x of the type-casted object matches the property of the current object a.
Answer: 2)Fishbone/lshikawa
Explanation: Fishbone diagrams are those diagrams which help in the identification of the problem causing factors and reasons behind.This diagrams find the roots of the problem to solve it. Fishbone diagram is also known as the Ishikawa diagram.
The other given options are incorrect because they are not any technique for finding the roots of the problem.Thus, the correct option is option(2).
