class Test {
  private int a;
  private int b;

 

  public Test() {
    a = 5;
    b = a - 3;
  }

 

  public int getA() {
    return a;
  }

 

  public int getB() {
    return b;
  }

 

  public void multiplyBy1000() {
    a *= 1000;
  }

 

  public void subtractSeven() {
   b -= 7;
  }

class Main {
  public static void main(String[] args) {
    Test m = new Test();
    System.out.println("a = " + m.getA() + ", b = " + m.getB());
    m.multiplyBy1000();
    System.out.println("a = " + m.getA() + ", b = " + m.getB());
    m.subtractSeven();
    System.out.println("a = " + m.getA() + ", b = " + m.getB());
  }
}
