JAVA输入输出流操作

//1 输入基本字节流
InputStream is = new FileInputStream("c:/1.txt");
//2 输入加强字节流
BufferedInputStream bis = new BufferedInputStream(is);
//3 输入基本字符流
Reader r = new FileReader("c:/1.txt");
//4 输入加强字符流
BufferedReader br = new BufferedReader(r);
String ss = br.readLine();

//1 输出基本字节流
OutputStream os = new FileOutputStream("c:/1.txt");
//2 输出加强字节流
BufferedOutputStream bos = new BufferedOutputStream(os);
//3 输出基本字符流
Writer w = new FileWriter("c:/1.txt");
//4 输出加强字符流
BufferedWriter bw = new BufferedWriter(w);
bw.newLine();
//5 输出加强字符流，可直接打开文本文件，println()比newLine()更好用
PrintWriter pw = new PrintWriter(w);
PrintWriter pw2 = new PrintWriter("c:/1.txt");
pw.println();
pw.println("1");

//文件节点流：FileInputStream、FileReader、FileOutputStream、FileWriter、PrintWriter
