接口(interface)是指只含有公有抽象方法(public abstract method)的类。这些方法必须在()中被实现。
为了支持压栈线程与弹栈线程之间的交互与同步,在程序的下画线处依次填入的语句是()。 public class IntStack{ private int idx=0; private int[]data=new int[8]; public void push(int i){ data[idx]=i: idx++; … … }
现有:  public interface A {}  以下哪项声明是合法的() 
已知结构Resource 的定义如下:struct Resource{public int Data = 0;}则下列语句的运行结果为()Resource[] list= new Resource[20];for(int i = 0;i<20;i++){System.Console.WriteLine(“data={0}”,list.Data);}
public class InterfaceDemo implements A,B{ @Override public void f(){ // TODO Auto-generated method stub }}interface A{ void f()throws IOException;}interface B{ void f()throws ClassNotFoundException;}
31、实现interface的方法前一定要用public修饰
以下代码运行后输出的内容()interface AAA{ void fun(); } class BBB extends AAA{ public void fun() { System.out.println("fun"); } } public class Main { public static void main(String[] args) { AAA a = new BBB(); a.fun(); } }
