NEW QUESTION 55
Which of the following can fill in the blank in this code to make it compile?

A. final
B. default
C. int
D. private
E. abstract

Answer: D

Explanation:
From Java SE 8, we can use static and/or default methods in interfaces, but they should be non abstract methods. SO in this case using default in blank is completely legal. Hence option C is correct. Option A is incorrect as given method is not abstract, so can't use abstract there. Options B and E are incorrect as we can't have non abstract method interface if they are not default or static. httpsy/docs.oracle.com/javase/tutorial/iava/landl/defaultmethods.html

Answer: E

Explanation:
The while statement is incorrect. It has the syntax of a for statement.
The while statement continually executes a block of statements while a particular condition is true. Its syntax can be expressed as:
while (expression) { statement(s) } The while statement evaluates expression, which must return a boolean value. If the expression evaluates to true, the while statement executes the statement(s) in the while block. The while statement continues testing the expression and executing its block until the expression evaluates to false.
