Java SO Example

Introduction

The java so example is extracted from the most popular open source projects, you can refer to the following example for usage.

Programming language: Java

Class/type: SO

Example#1
File: Example198.javaProject: nielspedersen/advanced-programming

 public static void main(String[] args) throws IOException, ClassNotFoundException {
   File f = new File("objects2.dat");
   if (!f.exists()) {
     System.out.println("Creating objects and writing them to file:");
     SC c = new SC();
     SO o1 = new SO(1, c), o2 = new SO(2, c);
     o1.c.ci = 3;
     o2.c.ci = 4; // update the shared c twice
     o1.cprint();
     o2.cprint(); // prints i1c4 i2c4
     OutputStream os = new FileOutputStream(f);
     ObjectOutputStream oos1 = new ObjectOutputStream(os);
     oos1.writeObject(o1);
     oos1.flush();
     ObjectOutputStream oos2 = new ObjectOutputStream(os);
     oos2.writeObject(o2);
     oos2.close();
     System.out.println("\nRun the example again to read objects from file");
   } else {
     System.out.println("Reading objects from file (non-shared c):");
     InputStream is = new FileInputStream(f);
     ObjectInputStream ois1 = new ObjectInputStream(is);
     SO o1i = (SO) (ois1.readObject());
     ObjectInputStream ois2 = new ObjectInputStream(is);
     SO o2i = (SO) (ois2.readObject());
     o1i.cprint();
     o2i.cprint(); // prints i1c4 i2c4
     o1i.c.ci = 5;
     o2i.c.ci = 6; // update two different c's
     o1i.cprint();
     o2i.cprint(); // prints i1c5 i2c6
     f.delete();
   }
   System.out.println();
 }

Example#2
File: PSO.javaProject: proverbs/MyRepo

 // 求一个基本交换序列作用于编码arr后的编码
 public void add(int[] arr, ArrayList<SO> list) {
   int temp = -1;
   SO s;
   for (int i = 0; i < list.size(); i++) {
     s = list.get(i);
     temp = arr[s.getX()];
     arr[s.getX()] = arr[s.getY()];
     arr[s.getY()] = temp;
   }
 }
