Question : What is FileOutputStream in java?

Java.io.FileOutputStream is an output stream for writing data to a File or to a FileDescriptor. Following are the important points about FileOutputStream:

• This class is meant for writing streams of raw bytes such as image data.

• For writing streams of characters, use FileWriter

public class FileOutputStream extends OutputStream

file = new File("c:/newfile.txt");
fop = new FileOutputStream(file);
if (!file.exists()) {
	file.createNewFile();
} 
// get the content in bytes
byte[] contentInBytes = content.getBytes(); 
fop.write(contentInBytes);
fop.flush();
fop.close();
