java IO流的使用

这是java输入流的使用语法格式，可以作为参考的类型

 

public class InputStream {
	public static void main(String[] args) {
		File file = new File("C:\\Example1.txt");

		try {
			if (!file.exists()) {
				file.createNewFile();
			}
			FileInputStream ff = new FileInputStream(file);
			byte[] bs = new byte[1024];
			StringBuilder sbBuilder = new StringBuilder();
			int a;
			while ((a = ff.read(bs)) != -1) {
				sbBuilder.append(new String(bs, 0, a));
			}
			ff.close();
			System.out.println(sbBuilder);

		} catch (IOException e) {
			e.printStackTrace();
		}

	}

}
