Solution
-
"Interface is better suited for Type declaration and abstract class is more suited for code reuse and evolution perspective." - This statement is correct. Interfaces are indeed used for declaring types in Java, while abstract classes are used for code reuse and evolution.
-
"You can extend only one abstract class" - This statement is also correct. In Java, a class can extend only one abstract class.
-
"You can create a non-abstract method in abstract class" - This statement is correct. In an abstract class, you can have both abstract and non-abstract methods.
-
"You can implement multiple inheritance in Java." - This statement is partially correct. Java does not support multiple inheritance with classes, but it does support multiple inheritance with interfaces.
-
"You can create a non-abstract method in an interface" - This statement is correct, but with a caveat. Prior to Java 8, interfaces could only have abstract methods. However, since Java 8, interfaces can have default and static methods, which are non-abstract.

Stat A) An abstract class is a class which contains some abstract methods as well as concrete methods also. Stat B) Consider that class that contains only abstract methods, and there are no concrete methods. It becomes an abstract class. Stat C) This means an interface is an abstract class but it contains only abstract methods. None of the methods in interface can be defined. Stat D) Only method names or headers can be written in interface. So that an interface can be defined as a specification of method headers.ABCD TrueACD TrueBCD TrueAD True
Which of the following statements about interfaces in Java is correct? Select one: The methods specified in the interface have a body enclosed by curly brackets. They are defined with the keyword "interface." The syntax is similar to that of a class, with the difference that no methods are abstract. They are defined with the keyword "abstract."
