class Test{undefined

private int m;

public static void fun() {undefined

// some code…

}

}

如何使成员变量m 被函数fun()直接访问?(　　)

public class Test {undefined

int x= 12;

public void method(int x) {undefined

x+=x;

System.out.println(x);

}

public static void main(String[] args){undefined

Test t = new Test();

t.method(5);

｝｝

则该方法属于(　　)。 

则该java源文件在存盘时的源文件名应为如下哪一种:(　　)

class A{undefined

public A(){undefined

System.out.print(“A”);

}

}

public class B extends A{undefined

public B(){undefined

System.out.print(“B”);

}

public static void main(String[ ] args){undefined

new B( );

}

}

程序的输出结果是
