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( ) { ... }} A．将 private int m 改为protected int m B．将private int m 改为public int m C．将private int m改为static int m D．将private int m改为int m
举一反三
- 给出如下代码: class Test{ private int m(){ ...... } public static void fun() { ...... } } 如何使成员函数m() 被函数fun()直接访问 A: 将private int m() 改为protected int m() B: 将private int m() 改为 public int m() C: 将private int m() 改为 static int m() D: 将private int m() 改为 int m()
- 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() { } }
- public class test { public static void main(String args[]) { int m=0; for ( int k=0;k<2;k++) method(m++); System.out.println(m); } public static void method(int m) { System.out.print(m); } }
- 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}}在 // point x安排哪个语句合法?
- 【多选题】给出如下代码 //接口 public interface Info { String show(int m, int n); } //类 public abstract class implements Info{ —————————— } 问:在类划线处,下列哪些定义是合法的?() A. public String show(int m, int n) {} B. public void show(int m, int n) {} C. protected String show(int m, int n) {} D. public Object show(int m,int n) {} E. public abstract String show(int m, int n); F. 其他定义都不合法
