Java Palindrome Checker Advanced String Manipulation
Hey everyone, welcome back to our Java programming journey!
"Mastering Java Palindrome Checker: Advanced String Manipulation"
Overview:
In this video, we'll explore a Java program that goes beyond the basics of palindrome checking.
We're dealing with sentences, ignoring spaces, punctuation, and case sensitivity.
I've divided the code into modular methods for a cleaner, more maintainable solution.
Code Walkthrough:
java
package com.qastring;
public class AdvancedPalindromeCheck {
public static void main(String[] args) {
// Input sentence to check for palindrome ("A man, a plan, a canal, Panama!")
String inputSentence = "A man, a plan, a canal, Panama!";
if (isPalindrome(inputSentence)) {
System.out.println("\"" + inputSentence + "\" is a palindrome.");
} else {
System.out.println("\"" + inputSentence + "\" is not a palindrome.");
}
}
private static boolean isPalindrome(String str) {
String cleanedString = str.replaceAll("[^a-zA-Z]", "");
String reversed = reverseString(cleanedString);
return cleanedString.equalsIgnoreCase(reversed);
}
private static String reverseString(String str) {
return new StringBuilder(str).reverse().toString();
}
}
Key Points:
We're working with a sample sentence: "A man, a plan, a canal, Panama!"
The program considers spaces, punctuation, and case sensitivity.
Methods like `isPalindrome` and `reverseString` make our code modular and maintainable.
Tips and Cheatsheet:
The program handles sentences, ignoring spaces, punctuation, and case sensitivity.
`isPalindrome` encapsulates the palindrome-checking logic.
`reverseString` efficiently reverses a string using `StringBuilder`.
Regular expressions (`[^a-zA-Z]`) remove non-alphabetic characters.
