Can you have String variable of just one character?

Hey Adiv,

You can certainly make a string equal a single character if you wish, it takes more overheard from resources but, it's certainly do able, this would unlock many methods on that string as well.

And yes, there are ways to check to see if a certain word is contained in string.

String.contains(); would be an easy and practical way to do this.

String example = "This is my example String";

boolean exampleContains() = example.contains("my");

In the above we're just setting up an example string, then setting a boolean value to if that word is contained in String, this would return true.

You could also pass in a value to check for if in a console environment like workspace using console, if in an IDE you can use a scanner, to keep it simple and assume console is made available.

String exampleString = "Another example string";
String wordToSearchFor = console.readLine("What word do you want to search for?");
boolean isContainedInExample = exampleString.contains(wordToSearchFor);

This will return true to the boolean value if the word that the user passes into console in contained in the String we want to check.

Based on it being true we can print a statement staying that it is, or whichever way you wanted to use that info.

Thanks, I hope this helps. Shout if it doesn't.
