1. Write a statement that will declare a two dimensional Integer array with 7 rows and 5 columns (10 pts).

2. Using the array above, write the code fragment that will initialize your array row by row from left to right beginning with the number 1 (1, 2, 3, 4, 5,6,7,8,9,10. etc). Use nested for loop. Do not hard code values nor loop control variable (20 pts).

public static void main(String[] args) { }

3. Write a java method called avgArray which takes as its parameters an int array and its size and returns the average of all the array elements and returns the same. (20 pts)

4. Mark the statements as TRUE or FALSE (5 pts)

1. The methods of a class must be public.

2. A constructor can have a value of int type.

3. A class can have more than one constructor.

4. Method definitions can be nested.

5. A method of a class that modifies the values of the data members is called Accessor method.

5. Write the default constructor for the below class (15 pts)

class Student { private String name; private int age; private String address;

}

6. Given the following code (10 pts)

public class Mystery { private int x; private double y;

public void print()

{

System.out.println(x+ +y););

}

public int sum()

{

return x+y;

}

}
