Messy Example 1

Code

ass Mess1 {
  public static void main (String[] arg) {
    int d;
    d=10;
    System.out.println(d);
    Ex1 g;
    g=new Ex1();
    g.a(d);
    System.out.println(d);
  }
}

class Ex1 {
  int p;
  
  Ex1() {
    p=0;
  }
  
  public void a (int p) {
    this.b(p);
    this.printVals(p);
    this.b(this.p);
  }

  private void b (int q) {
    this.printVals(q);
  }

  private void printVals(int r) {
    System.out.println(r);
  }
}

Output

Messy Example 2

Code

class Mess2 {
  public static void main (String[] arg) {
    int d,e;
    d=4;
    e=6;
    System.out.println(d + " " + e);
    Ex2 g = new Ex2();
    g.a(d,e);
    System.out.println(d + " " + e);
  }
}

class Ex2 {
  int p;
  
  Ex2() {
    p=3;
  }
  
  public void a (int p, int r) {
    this.b(r,p);
    this.printVals(p,r);
    this.b(this.p,r);
  }

  private void b (int p, int r) {
    this.printVals(p,r);
    this.printVals(this.p,r);
  }

  private void printVals(int p, int r) {
    System.out.println(p + " " + r);
  }
}

Output
