During your IT interview, you may be asked to determine if a string is a palindrome in Java. Let us tell you everything you need to know about palindromes and how to identify them so that you can provide a complete answer to your interviewers.
What Is a Palindrome in Java?
This is the main thing you need to know if you are going to come up with a code that can identify it. A palindrome is a word that is the same when read from left to right and when read from right to left. To get a better idea, let us give you a few examples.
Even if you read them from left to right or from right to left, words like “noon”, “rotor”, “level”, “madam”, “anna”, “racecar”, “kayak” are exactly the same.
Java palindromes are essentially strings that can be read from left from left to right or from right to left and remain exactly the same. Therefore, this is exactly how we can determine whether or not a string is a palindrome in Java.
Examples of Functions that Could Determine If a String Is a Palindrome in Java
There are many ways you can do create a function able to determine if a string is a palindrome. Depending on the requirements expressed by the interviewer, you can write a simple one or a more complex code that will go into details.
For instance, of factor that might affect your code is whether or not you consider lower cases and upper cases as different. “Noon” is a palindrome, but read backwards as it is written here, it would be “nooN”. So this is one feature that you might want to include in your code.
