Question

What does the following code do?

String w3 = "aardvark";
System.out.println(w3.substring( ()-2));

Answer 1

The code attempts to print a substring of the string 'aardvark', likely the last two characters, but there's a typo in the code snippet. The correct method to extract a substring is w3.substring(), and it would print 'rk' if the missing part is fixed to w3.length()-2.

Step-by-step explanation:

The provided code snippet is in Java and it is meant to print a substring of the string w3, which has been assigned the value "aardvark". However, there appears to be a typo or missing content inside the parenthesis for w3.substring(). Assuming the intention is to print the last two characters of the string "aardvark", the correct code should be System.out.println(w3.substring(w3.length()-2)) which would print "rk". The method substring in Java is used to extract a portion of a string starting from a specified index up until the end of the string or up to another specified index.
