Question

Suppose s is a string with the value "java". What will be assigned to x if you execute the following code? char x - s.charAt(4); 'a' 'V' Nothing will be assigned to x, because the execution causes the runtime error String Index Quit of Bounds Exception. None of above If a class named Student has a constructor Student (String name) defined explicitly, the following constructor is implicitly provided public Student() protected Student() private Student() Student() None Suppose the xMethod() is invoked from a main method as follows, xMethod() is public static void main(String[] args) {xMethod();} a static method an instance method None of the above

Explanation / Answer

Answers:

15. c. because "java" is of length 4. Indexing starts from 0. hence the last index for the string s is 3. Hence this will throw StringIndexOutOfBoundsException

16. e. because default implicit constructors will be provided by JVM only when there is no constructor defined. If there is a constructor explicitly defined in the class, then JVM will not provide default constructor.

17.a. since main method in java is a static method, any method calls will be only to static methods.
