java abstract class constructor & extends?

I need to Initialises the people, and set the name & weight of them as below

here it is : john , 55

alan , 45

joe , 40

alice, 40

kate , 60

public abstract class people {

public String john, alan, joe, alice, kate;

public people(String name, int weight)

{

weight = 55;

weight = 45;

weight = 40;

weight = 40;

weight = 60;

name = john;

name = alan;

name = joe;

name = alice;

name = kate;

}

public String getName()

{

return name; // ????

}

}

public class john extends people {

public john()

{

super(); // cant find symbol - constructor people()!!

weight = 55;

}

so basically , what I'm tring to do is Initialises both super&sub

class but it won't work. And i was trying to make a method that return

the name and another returning the weight but i can't .

I'm quite new to java stuffs so it would be very kind if you

point me to the right direction.

btw. cant change/touch any of method signature.
