To answer this question, let's go through each option and analyze the code snippet provided:
Option A) The code will compile and print "Equal".
In the given code snippet, the trim()
method is used to remove leading and trailing whitespace from the string " String "
. The trim()
method returns a new string with the whitespace removed.
However, when comparing strings, the ==
operator checks for reference equality, not value equality. In Java, the ==
operator compares the memory addresses of the objects being compared.
In this case, the string " String "
is not the same object as the string "String"
, even though they have the same value after trimming. Therefore, the ==
comparison will evaluate to false
.
So, the code will not print "Equal".
Option B) The code will compile and print "Not Equal".
As explained in Option A, the ==
comparison will evaluate to false
because the strings being compared are different objects. Therefore, the code will print "Not Equal".
Option C) The code will cause a compiler error.
There is no compilation error in the given code. The code is syntactically correct, and there are no issues that would cause a compiler error.
Option D) (No option provided)
This is not a valid option.
The correct answer is A) The code will compile and print "Equal".
