Write to File in Java
Used to create and write characters to a file.
Syntax
import java.io*;
//create a new File object
File fileObject = new File(filenamePath);
fileObject.createNewFile(); //in case the file does not exist
//create a FileWriter object
FileWriter fw = new FileWriter(fileObject);
//characters or strings to write
fw.write(contentToWrite);
fw.close();Notes
There are other classes that can be used to write to a file, including BufferedWriter, and OutputStreamWriter. These are used to write other character sets to files.
In order to prevent a memory leak, the writer must be closed.
Example
import java.io*;
File file = new File("marks.txt");
FileWriter fw = new FileWriter(file);
//characters or strings to write
fw.write("80 85 88 75 70");
fw.close();
