hi guys
I need urgent help with my project. I need to use this code

s[++size]=h[code].suffix;
code=h[code].prefix;

where the data type of "s" is int array whereas I dont know what data type "h" should be. when i tried it as "int", im getting this error int cannot be dereferenced. whats the problem here? should i include any import statements for solving this? what data type must "h" be?

Please help me out. URGENT

Hi,

Welcome to JavaRanch!

"h" looks to be an array of some class that has member variables named "suffix" and "prefix"; i.e.,

SomeUnknownClass[] h;

Since we don't know what "SomeUnknownClass" is, I can't tell you if import statements are needed. It might be a class you're supposed to write. Note that "suffix" and "prefix" aren't keywords in Java; they have no special meaning. They must just be variable names.

thanks you, will look into that.

Also is there a class name Element?. I also have this problem in the coding
h[codeUsed++]=new Element(pcode,s[size]);

And this line is showing error on compiling "cannot find symbol"

is there any package/class which i should import? or it is also another user-defined class?

There obviously is a class called Element. You can try going through the API documentation, where "Element" appears five times, but I suspect, as Ernest is hinting, that it is either a class you have to write yourself, or a class your teacher is giving you.

You haven't provided enough information for us to help you properly, and I think you need to go back to whoever set the assignment and ask for more information about where to find these classes. Have you got a sheet of instructions for your project? Does it say anything about Element or what "h" is?

I don't think any of the 5 Elements I found matches your code, so it is obviously something you have to write yourself, OR something your instructor has provided. And "h" would appear to be an array of Elements.
 
I agree. Here's the link: http://aspose.com/file-tools
