java - Just need some enlightenment about .equals -

-

this question has answer here:

integer = new integer(1); integer b = new integer(1); long c = new long(1);  system.out.println(a.equals(b)); system.out.println(a.equals(c));

question why a.equals(c) gives false?

from integer.equals():

the result true if , if argument not null , integer object contains same int value object.

c not integer, a.equals(c) returns false.
