Finding Array Element Index in Java?

[stripes]

Homework Statement

If I am given a regular, single dimensional array in Java, how do I search for an element in it, and then how do I get the index of that element?

I have been trying:

int largest;  //some number that has been predetermined in earlier code
int index3 = data.indexOf(largest);

But it keeps giving me errors in compiling. This method doesn't exist or something. I've read online and indexOf is very confusing. Not sure why I can't simply look up the format of it. I always figured it was

int number = stringName.indexOf(whatyou'researchingfor);

and then I can use 'number' later on as the index at which 'whatyou'researchingfor' showed up.

Is the data variable your array? If so, you can't directly evaluate it that way (array doesn't have an indexOf method). You need to create a loop and examine the String values in the array one at a time.
