1. public class Person { 2. private String name; 3. public Person(String name) { this.name = name; } 4. public boolean equals(Person p) { 5. return p.name.equals(this.name); 6. } 7. } Which is true?()
package foo; public class Outer { public static class Inner { } } Which statement is true?()
Given the following code: public class Person{ int arr[] = new int[10]; public static void main(String a[]) { System.out.println(arr[1]); } } Which statement is correct?()
package foo; public class Outer ( public static class Inner ( ) ) Which statement is true?()
Given the following code: public class Person{ static int arr[] = new int[10]; public static void main(String a[]) { System.out.println(arr[1];) } } Which statement is correct?()
有如下代码:public class Person { … }下列哪个符合该类的构造方法定义
存在以下JavaBean和JSP页面:Person.java:package x;public class Person {String name;public String getName() {return name;}public void setName(String name) {this.name = name;}}index.jsp:访问http://localhost:8080/项目名/index.jsp?name=John时的页面输出为
执行下面代码,下面描述正确的是( ) public class Person{ static int arr[]=new int[10]; public static void main(String a[]){ System.out.println(arr[1]); } }
请看如下代码 class Person {private int a;public int change(int m){return m;}}public class Teacher extends Person{public int b;public static void main(String arg[]){Person p = new Person();Teacher t = new Teacher();int i;// point x}}下面哪些放在// point x?行是正确的?
下列代码段中声明了3个类: Class Person{}; Class Student:publiC Person{}; Class Undergraduate:Student{}; 下列关于这些类之间关系的描述中,错误的是()。
已知定义public class Employee public class Manager extends Employee public class Contr已知定义public class Employee public class Manager extends Employee public class Contractor extends Employee Employee e=new Employee()
下列程序运行后的输出结果是()。includeincludeusing namespace std;class Person{public:
class Person{ String name,department; int age; public Person(Stringn){name=n;} public
对于类定义:class A{public:virtual void func1(){}void func2(){}};class B:public A{public:
给出下面代码: public class Person{ static int arr[] = new int[10];public static void main(String a[]) {System.out.println(arr[1]); } } 那个语句是正确的()。
给出下面代码: public class Person{ static int arr[] = new int[10];public static void main(String a[]) {System.out.println(arr[1]); } } 编译时正确,运行时将产生错误是正确的。()
给出下面代码: public class Person{ static int arr[] = new int[10];public static void main(String a[]) {System.out.println(arr[1]); } }()是正确的。
给出下面代码: public class Person{ static int arr[] = new int[10];public static void main(String a[]) {System.out.println(arr[1]); } } 哪个语句是错误的()。
给出下面代码: public class Person{ static int arr[] = new int[10];public static void main(String a[]) {System.out.println(arr[1]); } }编译时将产生错误)是正确的。()
给出下面代码: public class Person{ static int arr[] = new int[10];public static void main(String a[]) {System.out.println(arr[1]); } } 哪个语句是正确的()。
Given the uncompleted code of a class:class Person { String name, department; int age; public Person(String n){ name = n; } public Person(String n, int a){ name = n; age = a; } public Person(String n,
若所有 print方法均为static,则其结果输出为 : import java.io.*; class Person{ public static void print(); } }
给定如下Java程序,Test类中的四个输出语句输出结果依次是 。 class Person { String name="person"; public void shout(); } }
