答案：

public class PoolPuzzleOne {
        public static void main (String[] args) {
            int x = 0;
            while (x < 4){
                System.out.print("a");
                if(x < 1){
                    System.out.print(" ");
                }
                System.out.print("n");
                if(x > 1){
                    System.out.print(" oyster");
                    x = x + 2;
                }
                if(x == 1){
                    System.out.print("noys");
                }
                if(x < 1){
                    System.out.print("oise");
                }
                System.out.println("");
                x = x + 1;
            }
        }
    }

最后一行输出10

public class EchoTestDrive {
        public static void main(String[] args){
            Echo e1 = new Echo();
            Echo e2 = new Echo();
            int x = 0;
            while(x < 4){
                e1.hello();
                e1.count = e1.count + 1;
                if(x == 4){
                    e2.count = e2.count + 1;
                }
                if(x < 5){
                    e2.count = e2.count + e1.count;
                }
                x = x + 1;
            }
            System.out.println(e2.count);
        }
    }

public class Echo {
        int count = 0;
        void hello(){
            System.out.println("helloooo...");
        }
    }

最后一行输出24

public class EchoTestDrive {
        public static void main(String[] args){
            Echo e1 = new Echo();
            Echo e2 = e1;
            int x = 0;
            while(x < 4){
                e1.hello();
                e1.count = e1.count + 1;
                if(x == 3){
                    e2.count = e2.count + 1;
                }
                if(x > 0){
                    e2.count = e2.count + e1.count;
                }
                x = x + 1;
            }
            System.out.println(e2.count);
        }
    }

public class Echo {
        int count = 0;
        void hello(){
            System.out.println("helloooo...");
        }
    }
