Language Fundamentals - Programming

Q1:

Which one of these lists contains only Java programming language keywords?

A class, if, void, long, Int, continue

B goto, instanceof, native, finally, default, throws

C try, virtual, throw, final, volatile, transient

D strictfp, constant, super, implements, do

E byte, break, assert, switch, include

ANS:B - goto, instanceof, native, finally, default, throws

All the words in option B are among the 49 Java keywords. Although goto reserved as a keyword in Java, goto is not used and has no function. Option A is wrong because the keyword for the primitive int starts with a lowercase i. Option C is wrong because "virtual" is a keyword in C++, but not Java. Option D is wrong because "constant" is not a keyword. Constants in Java are marked static and final. Option E is wrong because "include" is a keyword in C, but not in Java.
