Solution for in-class exercise (Feb. 18th). The program reads elements of an array from the user's input.

import java.io.*;

public class ReadIntArray {

    public static void main (String [] args) throws IOException {
	// Create a buffered reader
	// need only one buffered reader for all your reading
	BufferedReader in = new BufferedReader(
			new InputStreamReader(System.in));
	// string for storing a line of input
	String line;

	// Read the length
	// prompt the user:
        System.out.print("Please enter the length: ");
	// read a line of input:
	line = in.readLine();
	// extract the integer from the entered data:
	int length = Integer.parseInt(line);

	// create the array
	int [] a = new int[length];
	
	// read the elements
	for (int i = 0; i < length; ++i) {
	    System.out.print("Please enter an element: ");
	    line = in.readLine();
	    a[i] = Integer.parseInt(line);
	}

	// print out the elements to check:
	for (int i = 0; i < length; ++i) {
	    System.out.println("a[" + i +"] = " + a[i]);
	}	
    }
}

This is an example from CSci 1211 course.
