How many times will the following loop execute? Write the output of the code:

int x=10; 
while (true){
System.out.println(x++ * 2);
if(x%3==0)
break;
} 

Which of the following are entry controlled loops?

(a) for

(b) while

(c) do..while

(d) switch

1. only a
2. a and b
3. a and c
4. c and d

To execute a loop 10 times, which of the following is correct?

1. for (int i=11;i<=30;i+=2)
2. for (int i=11;i<=30;i+=3)
3. for (int i=11;i<20;i++)
4. for (int i=11;i<=21;i++)

Define a class to accept a number and check whether it is a SUPERSPY number or not. A number is called SUPERSPY if the sum of the digits equals the number of the digits.

Example1:

Input: 1021
output: SUPERSPY number [SUM OF THE DIGITS = 1+0+2+1 = 4,
NUMBER OF DIGITS = 4 ]

Example2:

Input: 125
output: Not an SUPERSPY number [1+2+5 is not equal to 3]
