Reading and Writing a Properties File

// Read properties file.

Properties properties = new Properties();

try {

properties.load(new FileInputStream(

"infilename"));

} catch (IOException e) {

}

// Write properties file.

try {

properties.store(new FileOutputStream(

"outfilename"), null);

} catch (IOException e) {
