The data would probably be inside an array. Write a write-loop that reads the array and checks every element if it is 12. Then break from the loop because you only need the first. After you print the result then write another while-loop that reads the array backwards and does the same thing.

On a side-note, change your class name and variable names to something less meaningless. Descriptive names for classes, variables, and methods are immensely helpful to both you and others who read the code.

Also, after 22 posts here you should get familiar with [code] [/code] tags and use them.
