Practical Coding in Java

Coding Exercises: File IO

saveStrings() function

Write a Processing-style saveStrings() function that saves an array of Strings to a file:

    void saveStrings(String filename, String[] data)

Note: see the write_data() function in the HelloFile example in this chapter.

FileHelper class

Write a class FileHelper that contains the two Processing-style functions loadStrings() and saveStrings() as static member functions.

class FileHelper
{
    static String[] loadStrings(String filename)
    {
        // ...
    }

    static void saveStrings(String filename, String[] data)
    {
        // ...
    }
}

Write a test program to test your FileHelper functions.
