给出下列代码,如何使成员变量m 被方法fun()直接访问?class Test{private int m;public static void fun(){...}}
以下代码运行输出是() class Man { private String name = Jack
以下代码运行输出是()class Man {private String name = \Jack
有如下程序:include<iostream>using namespace std;class sample{private:int x,y;public:sampl
若有以下程序:include<iostream>using namespace std;class A{private:int a;public:A(int i){a
给出下面的程序代码:public class X4_1_3 { private float a; public static void m ()访问
某java程序的类定义如下: public class MyClass extends BaseClass{ } 则该java源文件在存盘时的源文件名应为
在下面的类定义中,错误的语句是class Sample{public:Sample(int val);//①~Sample(): //②private:
以下语句能顺利通过编译: class class1 { private final method1() {} } 。()
有以下程序:include<iostream>using namespace std;class sample{private:int n;public:sample(
3、下面程序段中,说法正确的是() class location{ public : int GetX(); }; class rectangle:private location { public: int GetW(); };
4、以下两个类在同一个Java源程序中, Class Adder { private int x; private int increase(int basic) { return basic+x; } } Class User { void use(int input) { Adder adder=new Adder(); int result=adder.increase(6); } } 红色的语句是不合法的。()
