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

NO.6 Given the code fragment:
Int [] [] array = {{0}, {0, 1}, {0, 2, 4}, {0, 3, 6, 9}, {0, 4, 8, 12, 16}};
Systemout.printIn(array [4] [1]);
System.out.printIn (array) [1] [4]);
What is the result?
A. 4 Null
B. Null 4
C. An IllegalArgumentException is thrown at run time
D. 4 An ArrayIndexOutOfBoundException is thrown at run time
Answer: D

Explanation:
The first println statement, System.out.println(array [4][1]);, works fine. It selects the element/array
with index 4, {0, 4, 8, 12, 16}, and from this array it selects the element with index 1, 4. Output: 4 The
second println statement, System.out.println(array) [1][4]);, fails. It selects the array/element with
index 1, {0, 1}, and from this array it try to select the element with index 4. This causes an exception.
Output: 4
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4

NO.7 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. Yellow
B. Maroon
C. Compilation fails
D. A StringIndexOutOfBoundsException is thrown at runtime.
