Java reads and writes file operation instance code through InputStream

1. File to InputStream

1	File File = new file ("File.xml");

2	InputStream InputStream = new FileInputStream (file);

2.InputStream to File

01	InputStream InputStream = new FileInputStream ("File.xml");

02

03	OutputStream outputstream = new FileOutputStream ("File-new.xml");
