PEN CLASS SOLUTIONS

TASK – PART 1 – SETUP

No solutions required.

TASK – PART 2 – PEN CLASS

Here is my solution (though many others are possible):

public class Pen

{

private int inkLeft;

public Pen(int ink)

{

inkLeft = ink;

}

public boolean isEmpty()

{

return inkLeft == 0;

}

public int getRemainingInk()

{

return inkLeft;

}

public void write(String s)

{

int i=0;

while (i < s.length() && inkLeft > 0)

{

char c = s.charAt(i);

System.out.print(c);

if (c != ' ')

{

inkLeft--;

}

i++;

}

}

}
