What is the difference between software design and the coding?

Answer 1

package collection; import java.util.List; import java.util.Vector; class Producer implements Runnable { private List list; public Producer(List pList) { list = pList; } publicvoid run() { System.out.println("Producer started"); for (int i = 0; i < 50; i++) { list.add(Integer.toString(i)); } System.out.println("Producer completed"); } } classConsumer implements Runnable { private List list; public Consumer(List pList) { list = pList; } publicvoid run() { System.out.println("Consumer started"); for (int i = 0; i < 50; i++) { while(!list.remove(Integer.toString(i))) { // Just } } } } public class VectorSyncEx { publicstatic void main(String[] args) throwsInterruptedException { List list = new Vector(); //List list = new ArrayList(); for (int i = 0; i < 10; i++) { Thread p1 = new Thread(new Producer(list)); p1.start(); } for (int i = 0; i < 10; i++) { Thread c1 = new Thread(new Consumer(list)); c1.start(); } System.out.println(list.size()); } } Try running the program with ArrayList. You can see a number of ArrayIndexOutOfBoundException, Consumer threads will still keep waiting for more elements which wont be added because the Producer has terminated after throwing the Exception

Design is the description of the logic used to solve the problem. Coding is the language/machine specific implementation of the design which runs on the computer and, hopefully, provides the expected result.
