java8 write file 写文件

1.用BufferedWriter写入文件

//Get the file reference
Path path = Paths.get("c:/output.txt");

//Use try-with-resource to get auto-closeable writer instance
try (BufferedWriter writer = Files.newBufferedWriter(path))
{
    writer.write("Hello World !!");
}

2.用 Files.write()写入文件

String content = "Hello World !!";
Files.write(Paths.get("c:/output.txt"), content.getBytes());
