Tulis menyang file nganggo BufferedWriter

import java.io.BufferedWriter; import java.io.File; import java.io.FileWriter; import java.io.IOException; public class WriteToFile {
public static void main( String[] args ) {
try {

String content = 'Content to write to file';

//Name and path of the file

File file = new File('writefile.txt');

if(!file.exists()){


file.createNewFile();

}

FileWriter fw = new FileWriter(file);

BufferedWriter bw = new BufferedWriter(fw);

bw.write(content);

bw.close();

} catch(IOException ex) {

System.out.println('Exception occurred:');

ex.printStackTrace();
}
} }
Cathetan:Yen pengin nambah file, kita kudu nggawe dhisikan FileWriter karo bener paramèter: FileWriter fw = new FileWriter(file, true);

Path path = Paths.get('writefile.txt');
String content = 'Content to write to file';

try {

byte[] bytes = content.getBytes();

Files.write(path, bytes);
} catch(IOException ex) {
