For example, you can construct a Writer that writes to a file easily using FileWriter: |
|
import java.io.FileWriter;
import java.io.IOException;
public class MainClass {
public static void main(String[] a) {
FileWriter writer;
try {
writer = new FileWriter("myFile.txt");
char c = 'A';
writer.write(c);
writer.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
