Java之使用IO流输入输出

题目

从文本文档输入沁园春，成一行排列。输出效果成古文形式排列，且输出到新的txt文档

代码

public class Test {

public static void main(String[] args) throws IOException {
	FileFormat();
	
}

public static void FileFormat() throws IOException{		
	String str = null;
	Test t = new Test();
	//字符流
	Reader r = new FileReader("C:\\沁园春.txt");
	Writer w = new FileWriter("C:\\1.txt");
	//缓冲流
	BufferedReader br = new BufferedReader(r);
	BufferedWriter bw = new BufferedWriter(w);
	try {
		while((str = br.readLine()) != null){
			System.out.println(str);
			System.out.println("读取完成");
			String[] s = t.init(str);
			for(int i = 0; i < s.length; i++){
				bw.write(s[i]);
				bw.write("。");
				bw.newLine(); 
			}
			System.out.println("写入完成");
		}
		bw.close();
		br.close();
		w.close();
		r.close();
	} catch (IOException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
}

 public String[] init(String str){
	  String[] s = new String[str.length()];
	  s = str.split("。");
	  return s;
	 }

}

效果
