1. interface TestA { String toString(); } 2. public class Test { 3. public static void main(String[] args) { 4. System.out.println(new TestA() { 5. public String toString() { return “test”; } 6. } 7. } 8. } What is the result?()
Given: 10.interface Data { public void load(); } 11.abstract class Info { public abstract void load(); } Which class correctly uses the Data interface and Info class?()
现有: interface Data {public void load();} abstract class Info {public abstract void load();} 下列类定义中正确使用Data和Info的是哪项?()
interface Data { public void load(); } abstract class Info { public abstract void load(); } Which class correctly uses the Data interface and Info class?()
interface foo { int k = 0; } public class test implements Foo ( public static void main(String args) ( int i; Test test = new test (); i= test.k; i= Test.k; i= Foo.k; ) ) What is the result? ()
现有: interface I { void go(); } abstract class A implements I { } class C extends A { void go(){ } } 结果是什么?()
class Ifs{ public static void main(String[] args){ boolean state=false; int i=1; if((++i>1)&&(state=true)) i++; System.out.println(i); } } 结果是()
现有: 1.class Passer f 2.static final int X=5; 3.public static void main (String [] args) { 4.new Passer().go (x); 5.System. out .print (x); 6. ) 7.void go (int x) { 8.System. out .print(x++); 9.} 10.}结果是什么?()
若有如下接口A的定义,下列哪些类下确实现了该接口( ) interface A {void method1(int i);void method2(int j);}
读程序写结果:#include void main(){ int i=8;switch (i){ case 9:i=i+1;default:i=i+1;case 10:i=i+1;case 11:i=i+1;}cout<
执行以下程序的输出结果是( )。void fun( ){static int a=1;a++;printf(“%d ”,a);}int main( ){int i;for(i=1; i<=2; i++) fun( );return 0;}
给定以下代码interface I { void f(); } abstract class C implements I {}下列哪行代码可以编译成功。
以下程序的输出结果是()。include <iostream.h>void main(){int a=0,i;for(i=1 ;i<5;i++){ switc
以下程序段的输出结果是[ ]。 include<iostream.h> void ref(int &i); void main(){int val=1
有以下程序include<iostream,h>int i=0;void fun(){{ Static int i=1 Std::cont<<i++<<','; } S
有以下程序:void sott(int a[], int n){ inti, j, t;for(i=0; i<n-1; i++)for(j=i+1; j<n; j++)i
Tilil程序的运行结果是()。 include<iostream.h> void main { int i=1: while(i<=8)
下面程序的运行结果是include<iostream.h>void main(){int i=1;while(i<=8)if (i%3!=2)cont
以下代码输出一个图形()。void main(){int i, j;for (i = 1; i <= 5; i++){for (j = 5; j >= i; j--){printf("*");}printf("\n");}}
include "stdio.h"void main(){int i;for (i=1;i<=5;i++){break;}printf(""%d"",i);}以上程序执行后,输出结果是
程序 include void main() { char str[][10]={ ”ok!”,“pen”,”book”,”desk”}; int i; for(i=1;i<3;i++) printf(“%s ”,str[i]); } 的执行结果是()
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;}
有以下程序: void main() int i; for(i=1; i<=40; 1++) if(i++%3==0) if(i%8==0) printf("%d",i); printf(""); 执行后输出的结果是()。
