Question

Java programming: Consider the following secret generic method:

Part I: What is returned by method secret() given the contents of the chains of nodes described below. show the trace

-chain1 is empty and chain2 is empty

-chain1 contains Integers 11, 22, 33 and chain2 contains Integers 33, 22, 11

-chain1 contains Integers 33, 55, 77 and chain2 also contains Integers 33, 55, 77

-chain1 contains Integers 99, 22 and chain2 contains Integers 99, 22, 44

-both chain1 and chain2 contain Strings "This", "is, "a", "test"

-chain1 contains Strings "Hello", "from", "the", "outside" and chain2 contains "Hello", "from", "the", "other side"

-chain1 contains Strings "The Cat", "in", "the Hat" and chain2 is empty

Part II: What does method secret() do in general? Do not just redescribe the code. Instead, briefly state what the method does at a high level (i.e., give its purpose).

Explanation / Answer

-chain1 is empty and chain2 is empty
true

-chain1 contains Integers 11, 22, 33 and chain2 contains Integers 33, 22, 11
false
chain1.getData()=11 != chain2.getData()=33

-chain1 contains Integers 33, 55, 77 and chain2 also contains Integers 33, 55, 77
True
chain1 and chain2 have same elements in same order

-chain1 contains Integers 99, 22 and chain2 contains Integers 99, 22, 44
False
chain1 has 2 elements only
chain2 has 3 elements
upto 2 iterations in while loop, if condition will be true.

-both chain1 and chain2 contain Strings "This", "is, "a", "test"
True

-chain1 contains Strings "Hello", "from", "the", "outside" and chain2 contains "Hello", "from", "the", "other side"
False
outside!=other side

-chain1 contains Strings "The Cat", "in", "the Hat" and chain2 is empty
False

partII

method secret() checks if two lists are same or not.
given list 1:[1,2,3,4]
list 2:[1,2,3,4]
it will return true, because they are same.
