Searching for a String in a String array

Question

while writing my program I have run into another nooby road block.

if(StringTerm[0].equals("wikipedia"))
        {
            StringBuilder SearchTermBuilder = new StringBuilder();
            for(int i = 1; i < StringTerm.length; i++)
            {
                SearchTermBuilder.append(StringTerm[i] + " ");
            }
            // This is the string it outputs. 
            WIKI_ID = "Wikipedia";
            SearchTerm = SearchTermBuilder.toString();
            SearchTermFull = WikiBaseLinkReference.WIKI_WIK + SearchTermBuilder.toString();
        }

This code checks for input from a console command "/wiki" and checks to see if the first string after the word "wiki" matches "wikipedia" and if so, it builds a string to match what I want it to do.

This is all well and good, and the program works fine, but I want users to be able to use different keywords to get the same results.

For Example: If I type /wiki wikipedia, it would do the same as /wiki pediawiki

If I made an array of different names called WIKIPEDIA

public static String WIKIPEDIA[] = {"wikipedia","pediawiki"};

How would I tell the if statement to check to see if the text entered equals one of the strings inside of my array? Every time I try to use an || or operator it throws me some errors.

Thanks in advance.

Please follow the Java naming conventions, and use lowercase letters at the beginning of your variable names. It'll increase the readability of your code. — jlordo, Aug 02 '13 at 20:49
Create a method that returns a `boolean` value and receives your array and checks if the value exists or not, and on that basis the method returns `true` or `false`. — Luiggi Mendoza, Aug 02 '13 at 20:49
Use `java.util.List` instead of default arrays. `List` have a `contains` method, that could provide test that you want to apply. — aim, Aug 02 '13 at 20:52

You need a version of "any":

public boolean any(String[] array, String s) {
    for(String value : array) {
        if(s.equals(value)) { return true; }
    }
    return false;
}

Then

if(any(WIKIPEDIA, "wikipedia")) {
}

This works. It took me a minute to figure out what was going on in that though, and even now I'm not entirely sure. Thanks for the good answer. – user2647089 Aug 02 '13 at 20:59
