Question

Review the methoddoStuff(). Can you successfully trace the output? Build a table where you can keep track of each variable in the loop and what is created by that loop.It's fairly easy to find ourselves "running around in circles" when we design nested For loops! Sufficient care must be devoted to carefully crafting each loop to provide the desired outcome.

public static void doStuff()
{
int lines, stars;
for (lines = 0; lines < 6; lines++)
{
for(stars = 0; stars<=lines; stars++)
System.out.print('*');
System.out.println();
}
}

Explanation / Answer

Lines Stars Output Output to Console 0 0 * * 1 0 * ** 1 * 2 0 * *** 1 * 2 * 3 0 * **** 1 * 2 * 3 * 4 0 * ***** 1 * 2 * 3 * 4 * 5 0 * ****** 1 * 2 * 3 * 4 * 5 *
