t3.ethincity="indian";
System.out.printf(t1.height);
System.out.printf(t2.weight);
System.out.printf(t3.ethincity);

t4.walk();

}}

Answer 1

Firstly remove the quotation marks around the values that you've assigned to the objects attributes and also the t3.enthincity attribute expects an integer value but you've assigned it a string value.

Answer 2

you have some mistake
you define ethicty as int then you put a string on it
i think your variable should be public and some another problem

Answer 3

you are passed string value in integer variable
try this :-
t1.height=6;
t2.weight=85;
and you have to change the dataType of ethincity variable
from integer to string.
