running JavaScript from Java?

Question

very new to coding and decided to start a project of mine. I watched a video on how to get it set up and started but after tinkering with it a little, I realized it was Java, not JavaScript. (Hey, i'm a noob at this) and I wanted an easier way to implement new things. this is what my main script looks like.

public void onMessage(String Message){
if(message.equals("Apples"){
sendMessage("You said apples!")}
else { 
if(message.equals("Oranges" //any text 
){
    sendMessage("you said Oranges and" //what they put for any text
)
 ...

Is there a way to take the bit that says Oranges and replace it by calling a JS function from another file?

Your question doesn't make a lot of sense. You're either running Java or you're running JavaScript (at least at this stage). Just write your program in one language. — Mike Cluck

Don't be fooled by the names, Java and Javascript are two totally different languages. It is a quirk of marketing history that they sound similar. If you are new to programming, definitely you only want to learn one language at a time. — user201891

Oh, but to answer your question "Is there a way to take the bit that says Oranges and replace it by calling a JS function from another file?" the answer is yes, but this is an incredibly advanced technique for a beginning programmer, as most programming languages do not interoperate easily. — user201891

Java and javascript are two completely different things. Java is a full programming language while Javascript is used to make websites dynamic , so it works inside a webbrowser. You should figure what you want and make a choice.

I was just trying to give a very brief overview. Obviously, "dynamic" is quite an understatement nowadays. The primary use of Javascript is still on the web 'though, while Java is used for offline, standalone applications more too.

Obviously there are other ways to interpret Javascript. I just stated the main application to give a beginning programmer some basic understanding. Feel free to correct me by going into all the details if you feel that adds something.

As others said, you need to figure out what you want.

Nevertheless, it is possible to run Javascript in java. Check javax.script package and check the docs: http://docs.oracle.com/javase/6/docs/technotes/guides/scripting/programmer_guide/index.html#evalfile
