Q1/
1. B (null)
2. C (a[0][2])
3. A (boolean)
4. C (Switch-case)
5. D (All of them)
6. A (for)
7. C (\n)
8. B (if(grade!=1))
9. index
10. D (column,row)

Q2/A

1. switch => Switch is a condition for switch-case statement, where the you write cases for it.

2. index => index is a position of an array element, starts from 0 to length of the array minus one.

3. Multidimensional arrays with two dimensions are often used to represent tables of values consisting of information arranged in rows and columns.

4. nested loop => A nested loop is a loop that appears in the loop body of another loop.

5. repetition statement => repetition statements that enable programs to perform statements repeatedly as long as a condition remains true.

Q2/B
1. False - String value
2. False - ||
3. False - %s
4. True
5. False - We don't need loop statement
6. True
7. True
8. False - without using counter value
9. True
10. False - Can Store Only one type of value

Q3/A
Counter-controlled repetition is often called definite repetition, because the number of repetitions is known before the loop begins executing.

Sentinel-controlled repetition is often called indefinite repetition because the number of repetitions is not known before the loop begins executing.

Q3/B
package javaapplication80;

public class JavaApplication80 {

    public static void main(String[] args) {
        int[][] a = {{0,1,2}, {3,4,5}, {6,7,8}, {9,10,11}};
        for (int row = 0; row < a[0].length; row++) {
            int total = 0;
            for (int col = 0; col < a.length; col++) {
                total += a[col][row];
            }
            System.out.println("Col" + row + ": " + total);
        }
    }
