Java Java Basics Perfecting the Prototype Censoring Words - Using String Equality

Can someone answer this

Ok I understand the equalsIgnoreCase() method. But what if you want to check if a String contains a particular String,ignoring the case

Example: String x = "I love Java"; now I want to check if the String x contains "Java" , ignoring the case

I know there is a method called contains , but no such thing as containsIgnoreCase So is there any solution

Hi there! I'm not aware of anything that will do a comparison with contains that ignores case. That being said, you can still accomplish this by making sure that everything is in the same case before you see if it "contains" that substring. I whipped up this code snippet for you. Feel free to run it in your workspace.

import java.io.Console;
public class Example {
  public static void main(String args[]) {

    Console console = System.console();    

    String language = "Java";
    String sentence = "I love java!";
    String lowerLanguage = language.toLowerCase();
    String lowerSentence = sentence.toLowerCase();

    if(lowerSentence.contains(lowerLanguage)) {
      console.printf("The sentence \"%s\" contains \"%s\" when ignoring case", sentence, language);

Hope this helps! :sparkles:
