Question mark "?" appears in output

Output:

No. of quarters: 4

No. of dimes: ? 10

No. of nicks: ? 20

No. of pennies: ? 100

Total amount is $4.0.

Code

public class CountChange {

public static void main(String [] args) {

int qrtrs, dimes, nicks, penns;

double total;

System.out.print("\nNo. of quarters: ");

qrtrs = TextIO.getInt();

System.out.print("No. of dimes: ");

dimes = TextIO.getInt();

System.out.print("No. of nicks: ");

nicks = TextIO.getInt();

System.out.print("No. of pennies: ");

penns = TextIO.getInt();

total = qrtrs*0.25 + dimes*0.10 + nicks*0.05 + penns*0.01;

System.out.print("Total amount: $");

System.out.println(total);

}

}

Correction

Replace getInt() with getlnInt()

Question

Why does "?" appear in the output? And why does it go away with getlnInt()?

Thanks
