Rewrite the following do while program segment using for:

x = 10; y = 20;
do
{
    x++;
    y++;
} while (x<=20);
System.out.println(x * y );

Give the output of the following program segment. How many times is the loop executed?

for(x=10; x>20;x++)

System.out.println(x);

System.out.println(x*2);

Consider the following two-dimensional array and answer the questions given below:

int x[ ][ ] = {{4,3,2}, {7,8,2}, {8, 3,10}, {1, 2, 9}};

(a) What is the order of the array?

(b) What is the value of x[0][0]+x[2][2]?

Differentiate between boxing and unboxing.
