QUESTION 14
Given the for loop construct:
for ( expr1 ; expr2 ; expr3 ) {
statement;
}
Which two statements are true?
A. This is not the only valid for loop construct; there exits another form of for loop constructor.
B. The expression expr1 is optional. it initializes the loop and is evaluated once, as the loop begin.
C. When expr2 evaluates to false, the loop terminates. It is evaluated only after each iteration through the loop.
D. The expression expr3 must be present. It is evaluated after each iteration through the loop.
1Z0-808 vce Correct Answer: BC
Explanation
Explanation/Reference:
The for statement have this forms:
for (init-stmt; condition; next-stmt) {
body
}
There are three clauses in the for statement.
The init-stmt statement is done before the loop is started, usually to initialize an iteration variable.
The condition expression is tested before each time the loop is done. The loop isn’t executed if the boolean expression is false (the same as the while loop). The
next-stmt statement is done after the body is executed. It typically increments an iteration variable.
QUESTION 15
Which three statements are true about the structure of a Java class?
A. A class can have only one private constructor.
B. A method can have the same name as a field.
C. A class can have overloaded static methods.
D. A public class must have a main method.
E. The methods are mandatory components of a class.
F. The fields need not be initialized before use.
1Z0-808 exam Correct Answer: ABC
Explanation
Explanation/Reference:
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
QUESTION 16
View the exhibit.

Given the code fragment:

Which change enables the code to print the following?

Williams age: 32
A. Replacing line 5 with public static void main (String [] args) throws MissingInfoException, AgeOutofRangeException {
B. Replacing line 5 with public static void main (String [] args) throws.Exception {

catch (missingInfoException e2) { //code goes here} catch (AgeOutofRangeException e3) {//code goes here}
D. Enclosing line 6 and line 7 within a try block and adding:
catch (missingInfoException e2) { //code goes here} catch (AgeOutofRangeException e3) {//code goes here}

Which two modifications, made independently, enable the code to compile and run?
A. Adding a break statement after each print statement
B. Adding a default section within the switch code-block
C. Changing the string literals in each case label to integer
D. Changing the type of the variable day to String
E. Arranging the case labels in ascending order
1Z0-808 vce Correct Answer: AC
