Question 1
In java, an array can contain several types of elements

True or False ?

Question 2

True or False ?

Question 3

int computeValue (int x, int y)
is a function which receives 2 parameters x and y, passed by reference

True or False ?

Question 4

There are 3 main logical operators in java:
&& (AND), || (OR), and ! (NOT)

Question 5

In java, when passing an entire array to a function as an argument, the default passing mechanism is by reference

Question 6

According to De Morgan's law,
!(A || B) is equivalent to !A || !B
Where ! means NOT and || means OR

True or False ?

Question 7

In Java, variable names are case sensitive, so myName is not the same as mynamE.

True or False ?

Question 8

Variable1 = Variable2, the content of Variable2 gets copied in Variable1.

True or False ?

Question 9

int computeValue (int x, int y)
is a function which returns an integer

True or False ?

Question 10

int computeValue (int x, int y)
is a function which receives 2 parameters x and y, passed by value

True False ?

Question 11

In Java, it is possible to have two functions by the same name as long as

1. they don't have the same number of parameters ?

3. The parameter list is not identical ?

4. They don't return the same type of value ?

5. Any of the above is true ?

Question 12

(a || b && c) is equivalent to

1. a || (b &&c) ?

2. (a || b) && c ?

3. why bother, it is all the same anyways?

Question 13

In java, Variable1 = Variable2 is the same as
Variable1 == Variable2

True or False ?

Question 14

in the following code:
int[] list = {1, 2, 3, 4, 1, 2, 3};

list[1] contains

options:

1?

2?

3?

4?

Question 15

int[][][] myArray = new int[2][3][4];

creates an array of

1. 24 integers ?

2. 24 elements, some of which are integers ?

3. 12 integers ?

4. 12 elements, some of which are integers ?

Question 16

According to De Morgan's law,
!(A && B) is equivalent to !A && !B
Where ! means NOT, && means AND and || means OR

True or False ?

Question 17

Is a set of rules which simplify complex logical equations

True or False ?

Question 18

In Java, && gets evaluated before ||

True or False ?

Question 19

When writing
Variable1 = Variable2,
the contents of Variable2 are tested against the contents of Variable1;
If they are equal, then the evaluation will yield true, otherwise it will yield false

True or False ?

Question 20

in the following code:
int myVal = computeValue(2, 3);

int computeValue (int x, int y) {
    int result = x+y;
    return result;
}

int myVal = computeValue(2, 3);
is

1. a parameter ?

2. A function call ?

3. the function body ?

4. the header of the function computeValue ?
