Given the variables

String stars = "*****";

String stripes = =====;

what do these loops print?

a. int i = 0;

while (i < 5)

{

System.out.println(stars.substring(0, i));

i++;

}

b. int i = 0;
while (i < 5)

{

System.out.print(stars.substrings (0, i));

System.out.println(stripes.substrings(i, 5));

i++;

}
c. int i = 0;
while (i < 10)

{

if (i % 2 == 0) { System.out.println(stars); }

else { System.out.println(stripes); }

//Check the condition using while loop

while (i < 5)

{

//Print the output

System.out.println(stars.substring(0, i));

//Increment the value of "i"

i++;

}

Explanation:

The above code snippet initializes the variable “i” to “0”. The condition “i<=5” is checked using “while” loop. Print the output and increment the value of “i”.
