b) 11.25

c) 11

d) 10

3) Assume:

int x[][] = {{ 1, 2 }, { 3, 4, 5 }, { 4, 5, 4, 9 }};

What are the values of?

x[ 0 ].length?

x[ 1 ].length?

x[ 2 ].length?

4) A class method can be overloaded by changing the number of arguments.

a) True

b) false

5) A class method can be overloaded by changing the return type.

a) True

b) False

6) A while loop will execute at least once?

a) True

b) false

7) A method is invoked by

a) writing the name of the method followed by a colon and the name of the calling object

b) writing the name of the calling object, followed by a dot, followed by the name of the method and a list of values in parentheses

c) writing the name of the calling object followed by a dot and a list of values in parentheses

d) listing the name of the calling object and the name of the method inside parentheses

Answer 1

1] value % divisor is 4. so option a.

2] value / divisor is 11. so option c.

3] x.length is 3, x[0].length is 2, x[1].length is 3, x[2].length is 4

4] A class method can be overloaded by changing the number of arguments is True. option a.

5] A class method can be overloaded by changing the return type is False. option b.

6] A while loop will execute at least once is false. so option b.

7] A method is invoked by writing the name of the calling object, followed by a dot, followed by the name of the method and a list of values in parentheses. for ex: obj.sum(2, 4). so option b.
