public class FileWriter {

public static void writeFile() throws Exception {

// 1、通过File找到一个文件

File file = new File("d:" + File.separator + "temp.txt");

// 2、实例化OutputStream对象

OutputStream out = new FileOutputStream(file);

String info = "Hello World!!!"; // 要输出的字符串

byte data[] = info.getBytes();// 将字符串变为字节数组

out.write(data); // 输出内容

out.close();

}

}
