NEW QUESTION # 58
Given:
And given the code fragment:
Book book1 = new EBook();
book1.readBook();
Which option enables the code to compile?
- A. Option B
- B. Option C
- C. Option A
- D. Option D
Answer: D
NEW QUESTION # 59
Given:
public class ColorTest {
public static void main(String[] args) {
String[] colors = {"red", "blue","green","yellow","maroon","cyan"};
int count = 0;
for (String c : colors) {
if (count >= 4) {
break;
}
else {
continue;
}
if (c.length() >= 4) {
colors[count] = c.substring(0,3);
}
count++;
}
System.out.println(colors[count]);
}
}
What is the result?
- A. Compilation fails
- B. A StringIndexOutOfBoundsException is thrown at runtime.
- C. Yellow
- D. Maroon
Answer: A
Explanation:
The line, if (c.length() >= 4) {, is never reached. This causes a compilation error.
Note: The continue statement skips the current iteration of a for, while , or do-while loop. An unlabeled break statement terminates the innermost switch, for, while, or do-while statement, but a labeled break terminates an outer statement.
NEW QUESTION # 60
Given the code fragment:
Which three lines fail to compile? (Choose three.)
- A. Line 10
- B. Line 8
- C. Line 9
- D. Line 11
- E. Line 7
- F. Line 12
Answer: A,E,F
NEW QUESTION # 61
Which three statements are true about the structure of a Java class?
- A. A class can have only one private constructor.
- B. A class can have overloaded static methods.
- C. A public class must have a main method.
- D. The fields need not be initialized before use.
- E. The methods are mandatory components of a class.
- F. A method can have the same name as a field.
Answer: A,B,F
Explanation:
A: Private constructors prevent a class from being explicitly instantiated by its
callers.
If the programmer does not provide a constructor for a class, then the system will always
provide a default, public no-argument constructor. To disable this default constructor,
simply add a private no-argument constructor to the class. This private constructor may be
empty.
B: The following works fine:
int cake() {
int cake=0;
return (1);
}
C: We can overload static method in Java. In terms of method overloading static method
are just like normal methods and in order to overload static method you need to provide
another static method with same name but different method signature.
Incorrect:
Not D: Only a public class in an application need to have a main method.
Not E:
Example:
class A
{
public string something;
public int a;
}
Q: What do you call classes without methods?
Most of the time: An anti pattern.
Why? Because it faciliates procedural programming with "Operator" classes and data
structures. You separate data and behaviour which isn't exactly good OOP.
Often times: A DTO (Data Transfer Object)
Read only datastructures meant to exchange data, derived from a business/domain object.
Sometimes: Just data structure.
Well sometimes, you just gotta have those structures to hold data that is just plain and
simple and has no operations on it.
Not F: Fields need to be initialtized. If not the code will not compile.
Example:
Uncompilable source code - variable x might not have been initialized
