Question

Array Data - Write two methods that read data from the console and store the data in an array:

a. The method:     

                      int readData(int [ ] x)

reads a list of at most 100 integers into the array x. A sentinel 999 terminates the list. The method returns the size of the list.

9. Largest and Smallest

Design a method that determines the largest and smallest values stored in an integer

array, x. Your method should return these values in an array of length two. Use the

following algorithm:

Initialize variables currentBig and currentSmall to the larger and smaller values

of x[0] and x[1]. Process the rest of the list, two elements at a time. Compare the

larger of the two elements to currentBig , and replace currentBig if necessary.
Compare the smaller of the two elements to currentSmall, and replace currentSmall  

if necessary. Test your method in a program and include a method that reads a list,

terminated by 999, into an array.

Explanation / Answer

Public class ReadInputDisplay{

public static ArrayList readData(String fileName) {
  String line = "";
  ArrayList data = new ArrayList();//consider using ArrayList<int>
  try {
   FileReader fr = new FileReader(fileName);
   BufferedReader br = new BufferedReader(fr);
   while((line = br.readLine()) != null) {

    data.add(line);

System.out.println(data.size());
   }
  }
  catch(FileNotFoundException fN) {
   fN.printStackTrace();
  }
  catch(IOException e) {
   System.out.println(e);
  }
  return data;
}

}
