    {

        //Initialize the variables

        String stars = "*";

        String stripes = "=====";

        //Initialize the value of "i" to 0

        int i = 0;

        //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”.

                //Print the output

                System.out.println(stars);

            }

            else

            {

                //Print the output

                System.out.println(stripes);

            }

        }

    }

}

Explanation:

The above code snippet initializes the variable “i” to “0”. The condition “i<=10” is checked using “while” loop. Inside the while loop, check the condition of “i%2” using the “if” statement.

        //Initialize the variables

        String stars = "*";

        String stripes = "=====";

        //Initialize the value of "i" to 0

        int i = 0;

        //Check the condition using while loop

        while (i < 10)

        {

//Check the condition for "i%2" equals to 0

            if (i % 2 == 0)
