3. What will be printed by the following code snippet?
int
i=0;
for
(i=2;i
<
25; i+=2)
{
if
( i %7==0)
{
break
;
}
}
System.out.println(i);

int
i=0;
for
(i=2;i
<
25; i+=2)
{
if
( i %7==0)
{
continue
;
}
}
System.out.println(i);
5. Rewrite the following code to use a
while
statement instead of the
for
loop.
for
(
int
i=0,j=0;i
<
10; i++)
{
j ++;
System.out.println(i+j);
}
6. Write a program that persistently asks the user to enter a positive number. The
program should only terminate when a positive number is entered. Use a
do-while
loop.
7. Rewrite the program from Question 6 to use an infinite
while
loop. That is,
while(true)
{
structure. Use a
break
statement to terminate the loop when
a positive number is entered.
...
}
8. Write a program that reads an integer from the keyboard and tells the user if the
number is prime. Use a
for
loop to check if the number is divisible by the numbers
from 2 up to the value of the input number minus 1.
9. Write a program that reads an integer from the keyboard and prints the corresponding
binary number.
10. Write a program that reads an integer from the keyboard and prints the factorial of
the input. Use a variable of type
long
to store the result.
11. A palindrome is a string that reads the same forward and backward. Write a program
that reads a string from the keyboard and tells the user if the string is a palindrome.

You will create a two-player version of the Hangman game. The program should first
ask for the first player to enter a word and save the word. Next, the second player should
