I've done some code to catch an error it catches it but then goes straight to it again

And prints like this

Enter Mark
(minus sign inputted to check for typing mistake) -
Wrong type of input
Exception in thread InputMismatchException blah blah

Here is the code

public static void GetID() //Function called to collect the student ID and eight marks
{

for (int c = 0; c < 2;c++)
{

System.out.println("Please Enter the student ID");
studentID[c] = kybd.next();


System.out.println("Please enter the eight exams marks");
for (int a = 0; a < 8; ++a)
{
System.out.println("Enter mark" + " " +( a + 1) + " ");
Error();
marks[c][a] = kybd.nextInt();

if (marks[c][a] > 20)
{
System.out.println("Entry out of score limit");
a = a ;
c = c ;
System.out.println("Enter mark" + " " +( a + 1) + " ");
Error();
marks[c][a] = kybd.nextInt();

}
else
if(marks[c][a] < -1 | marks[c][a] == 0)
{
System.out.println("Entry out of score limit");
a = a ;
c = c ;
System.out.println("Enter mark" + " " +( a + 1) + " ");
Error();
marks[c][a] = kybd.nextInt();

}





}

}
Display();
}

public static void Error()
{
try
{
marks[c][a] = kybd.nextInt();

}
catch (InputMismatchException ime)
{
System.out.println("Wrong type of input");

}
}
