下列语句错误的是:( )
A: ServerSocket svrsoc= new ServerSocket(8000);
B: URL urlBase=new URL(“http://www. zjut.edu.cn/”) ;
C: File inFile = new File(“C:/ test.txt”);
D: BufferedReader br = new BufferedReader(“C:/ test.txt”);
A: ServerSocket svrsoc= new ServerSocket(8000);
B: URL urlBase=new URL(“http://www. zjut.edu.cn/”) ;
C: File inFile = new File(“C:/ test.txt”);
D: BufferedReader br = new BufferedReader(“C:/ test.txt”);
举一反三
- 以下哪个语句可以在窗口中为c:\temp.txt创建一个File实例。() A: new<br/>File("c:\temp.txt") B: new<br/>File("c:\\temp.txt") C: new<br/>File("c:/temp.txt") D: new<br/>File("c://temp.txt")
- 下列写法错误的是 A: File f = new File ("a.txt"); B: File f = new File ("d:\\a.txt"); C: FileInputStream fis = new FileInputStream (new File ("a.txt")); D: FileOutputStream fos = new FileOutputStream ( File ("."));
- 3.1 下面是创建File对象的语句,错误的是( ) A: File f=new File("d:\\text.txt"); B: File f=new File("d: "); C: File f=new File("d:","text.txt"); D: File f=new File("d:\text.txt");
- 要读一个较大的文件，下列创建对象的方法中哪个是最合适的？（ ） A: new FileInputStream(“myfile.dat”); B: new InputStreamReader(new FileInputStream(“myfile.dat”)); C: new BufferedReader(new InputStreamReader(new FileInputStream(“myfile.dat”); D: new RandomAccessFile raf=new RandomAccessFile(new File(“myfile.dat”,”rw”));
- 中国大学MOOC: 语句BufferedReader in = new BufferedReader( new InputStreamReader( clientSocket.getInputStream()))，从网络读入的是：
