What I learned…errr last night was about using multiple strings with formatters in Java. For instance:

String name = “Tiffany”; String age = 30; console.printf(“My name is %s and I am %s years old.”, name, age); String name = “Tiffany”; String age = 30; console.printf(“My name is %s and I am %s years old.”, name, age);  This is sort of like when I was doing Learn Python the Hard Way only the syntax is different and more verbose. I learned how to get information into the console by way of prompting the user. So you have the console object and the method readLine to say something like: console.readLine(“What is your name?”); console.readLine(“What is your name?”); console.readLine(“What is your name?”);  This was interesting, getting to learn these new methods for a new language. Also knowing the Java is compiled and how to run the compile command with: javac javac javac  I learned more about integers and getting an integer from a string. Whereas in JavaScript you’d use: parseInt parseInt parseInt  in Java you have this long string: Integer.parseInt Integer.parseInt Integer.parseInt  Building things and adding conditions was interesting as well. Here is a little snippet of the app we built in Java: String name = console.readLine(“Enter a name: ”); String adjective = console.readLine(“Enter an adjective: ”); String noun; boolean isInvalidWord; do { noun = console.readLine(“Enter a noun: ”); isInvalidWord = (noun.equalsIgnoreCase(“dork”) || noun.equalsIgnoreCase(“jerk”)); if (isInvalidWord) { console.printf(“That language is not allowed. Try again. \n\n”); } } while(isInvalidWord); String name = console.readLine(“Enter a name: ”); String adjective = console.readLine(“Enter an adjective: ”); String noun; boolean isInvalidWord; do { noun = console.readLine(“Enter a noun: ”); isInvalidWord = (noun.equalsIgnoreCase(“dork”) || noun.equalsIgnoreCase(“jerk”)); if (isInvalidWord) { console.printf(“That language is not allowed. Try again. \n\n”); } } while(isInvalidWord);  To be honest, Java isn’t really too bad. I don’t like the verbosity. For instance in JavaScript you can call a method: noun.toLowerCase noun.toLowerCase noun.toLowerCase  instead of what we’ve got here in Java. Java is a little better in that the .equalsIgnoreCase makes things simpler so I could call it on any object and the case would be ignored completely. But it just looks cleaner. So that was my experience fo Java Beginner Basic Course on Treehouse. I plan on diving deeper as the semester grinds on. For now, it’s learning RegEx and then back to JavaScript as I want to start thinking about building my app.
