Java读写文件的方法

Java读写文件的方法有很多种形式，分享一下我整理出来的一种情况。

一、读文件：

public static void ReadFile() {
		String file_path = "data/newFilename.txt";
		try (FileReader reader = new FileReader(file_path); BufferedReader br = new BufferedReader(reader)) {
			String line;
			while ((line = br.readLine()) != null) {
				System.out.println(line);
			}
		} catch (IOException e) {
			e.printStackTrace();
		}
}

二、写文件：

public static void WriteFile() {
		try {
			File file = new File("data/newFilename.txt");
			file.createNewFile();
			try (FileWriter writer = new FileWriter(file); BufferedWriter out = new BufferedWriter(writer)) {
				out.write("hello,");
				out.write("world!");
				out.write("ok");
			}
		} catch (IOException e) {
			e.printStackTrace();
		}
}

具体怎么用，或者你想怎么用，自己再变形吧。
