What output is produced by the following code int top 4 n

What output is produced by the following code?

int top = 4, n = -1;

while( n <= top)

{

switch(n)

{

case 1:

System.out.println(\"ONE.\");

break;

case 3:

System.out.println(\"Three.\");

break;

case 4:

System.out.println(\"Four.\");

break;

default:

System.out.println(\"Default case.\");

break;

}

n++;

}

Note: This is Java programming

Solution

n = -1

it will print Default case.

n = -1+1 = 0

it will print Default case.

n = 0+1 = 1

it will print ONE.

n = 1+1 = 2

it will print Default case.

n = 2+1 = 3

it will print Three.

n = 3+1 = 4

it will pring Four.

Hence the output is :

Default case.

Default case.

ONE.

Default case.

Three.

Four.
