【填空题】阅读程序写结果 public class Student { private static int sid = 0; private String name; int id; Student(String name) { this.name = name; id = sid++; } public void info() { System.out.println("My name is "+name+" No."+id); } public static void infoSta() { System.out.println(sid); } public static void main(String arg[]) { Student.sid = 100; Student st1 = new Student("huahua"); st1.sid = 2000; Student st2 = new Student("meimei"); st1.info(); st2.info(); } }
举一反三
- 下面程序运行的结果是 struct Student { public int age; public string name; public Student(int age, string name) { this.age = age; this.name = name; } } class Program { static void Main(string[] args) { Student stu1 = new Student(18, "小方"); Student stu2 = new Student(24, "小刚"); stu2 = stu1; stu1.age = 30; stu1.name = "小燕"; Console.WriteLine("{1},{0}",stu2.age,stu2.name); } }
- 下列程序的运行结果是（ ）class Demo{private String name;Demo(String name){this.name = name;}private static void show(){System.out.println(name)}public static void main(String[] args){Demo d = new Demo(“lisa”);d.show();}}
- （6-3）阅读程序，写出程序运行结果。 class Book{ private static int counter=0; private int id=1; private String name; public Book(String name) { this.name = name; counter++; this.id=this.id+8; } public static int getCounter() { return counter; } public int getID() { return this.id; } } public class BookDemo{ public static void main(String[] args) { Book b1=new Book("红楼梦"); Book b2=new Book("西游记"); Book b3=new Book("儒林外史"); System.out.println(b3.getCounter()*Book.getCounter()*b3.getID()); } }
- 在C#中，下列代码的运行结果是( )（选一项）[br][/br] struct Student { public int age; public string name; public Student(int age,string name) { this.sge = sge; this.name = name; } } public class Test { static void Main() { Student stu1 = new Student(18,"小芳"); Student stu2 = new Student(24,"小刚"); stu2 = stu1; stu1.age = 30; stu1.name = "小燕"; Console.WriteLine(stu2.age); Console.WriteLine(stu2.name); } } A: 18 小芳 B: 18 小燕 C: 30 小燕 D: 30 小芳
- 【填空题】public class ThisTest{ private String name; private int age; public ThisTest() { System.out.println("产生一个新的Person对象。"); } public ThisTest (String name, int age) { this(); this.name = name; this.age = age; } public String getInf() { return "姓名:" + name + ",年龄:" + age; } public static void main(String[] args) { ThisTest per = new ThisTest("张三", 20); System.out.println(per.getInf()); } } 运行结果为:____
