Of course I'd prefer to know how to do it than ask you for a solution.
This is what I've got :
package tma01q1;
public class ISPN
{
private int[] authorId;
private int[] programId;
/**
* Creates a new instance of ISPN
*/
public ISPN(int[] anAuthorId, int[] aProgramId)
{
//here i am not sure how to declare array arguments
}
public boolean isValidLength()
{
while
{
anAuthorId + aProgramID == 6
}
return true;
}
public boolean isAllValidDigits()
{
while
{
(anAuthorID >= 0 && anAuthorID <= 9) && (aProgramID >= 0 && aProgramID <= 9)
}
return true;
}
