public class Employee
{

	private String name;
	private String number;
	private boolean valid=true;


	public Employee(String nm, String num)
	{
		name=nm;
		number=num;

		if(number.length()!=5)
		valid=false;
		for(int i=0; i<3; i++)
		{
			if(!Character.isDigit(number.charAt(i)))
			valid=false;
		}

		if(number.charAt(3)!='-')
		valid=false;

		if(!Character.isLetter(number.charAt(4)))
		valid=false;
		else
		{
			if(number.charAt(4)!='A'||number.charAt(4)!='B'||number.charAt(4)!='C'||number.charAt(4)!='D'||number.charAt(4)!='E'||
			number.charAt(4)!='F'||number.charAt(4)!='G'||number.charAt(4)!='H'||number.charAt(4)!='I'||number.charAt(4)!='J'||
			number.charAt(4)!='K'||number.charAt(4)!='L'||number.charAt(4)!='M')
			valid=false;
		}
	}

	public boolean getNum()
	{
		return valid;
	}



}

public class work extends Employee
{
	private int shift;

	public work(int sh)
	{

you're missing a default constructor within Employee

public Employee(){
     this.name = "name";
     this.number = 0;
}

I think it's either that or your employee class isnt located in the same file as your work class.

I put both class file under the same folder.
then, I have try to change the default constructor as you said, but I still get the same error.
why it will like that?..

i think that because your subclass "work" has no default constructor defined, by definition it calls its superclass' default constructor, which doesn't exist as well.
