三、转换流(InputStreamReader,OutputStreamWriter) 用于实现将字节流转换成字符流。 System.in代表标准输入,即键盘输入。输入的内容是InputStream类的实例,用InputStreamReader将其转换成字符输入流,但是普通的Reader读取时依旧不方便,可以将普通的Reader再次包装成 BufferedReader,利用BufferedReader的readLine()方法可以一次...
如CharArrayReader:和ByteArrayInputStream的作用都是把内存中的一个缓冲区作为InputStream使用,所不同的是前者每次从内存中读取一个字节的信息,而后者每次从内存中读取一个字符。 1.3 两种不现导向的stream之间的转换 InputStreamReader和OutputStreamReader:把一个以字节为导向的stream转换成一个以字符为导向的stream。
读取的数据顺序必要要与写入一致,下面代码与DataOutputStream的代码示例顺序一致,可以正常读取。 代码示例: publicstaticvoidread1()throwsIOException {// 创建一个文件输入流,做为节点流FileInputStreamfis=newFileInputStream("c:/io/12_1.txt");// 创建一个数据输入流,做为转换流DataInputStreamdis=newDataInput...
input为字符串,int强制转换成整形;多组例子使用while n=int(input()) #3 s=input().split(',') #1,2,3 try: n,m = map(int,input().split()) #2 5 except: break b = list(map(int,input().split())) #2 3 5 6 9 2.输出: ...

There are two basic categories, so the java.io package includes two abstract classes ( InputStream and OutputStream). subarray An array that is inside another array. subclass A class that is derived from a particular class, perhaps with one or more classes in between. See also superclass,...
在Java中可以使用ZipOutputStream和ZipInputStream来实现zip的压缩和解压缩操作,另外使用FileSystem也可以用来实现zip的解压缩,下面将介绍这几种方式,直接上代码。 zip压缩 待压缩文件目录结构: 每个zip文件项都要对应一个ZipEntry,然后通过ZipOutputStream的putNextEntry方法开始写入一个新的zip文件项,将文件数据发送到zip...
