Add to Lehrer class:
?
1
2
3
4
public Lehrer()
{
    super("", (char)0, 0, 0, false);
}
Or, add to Mensch class:
?
1
2
3
public Mensch()
{
}
However, be it known that a Lehrer object IS a Mensch object because of class hierarchy. If you intended the classes to create different type objects (not just a more defined similar type), then one should not subclass the other.
