Java - Reading the text content from file with out loop through

Reading the text content from file with out loop through.

Sample Program:
import java.io.IOException;
import java.nio.charset.Charset;
import java.nio.file.Files;
import java.nio.file.Paths;

public class ReadFile {
public static void main(String[] args) throws IOException {
byte[] encoded = Files.readAllBytes(Paths.get("C:\\filename.txt"));
String fileContent = new String(encoded, Charset.defaultCharset());

System.out.println(fileContent);
}
}


Reading the text content from File using 'while' loop.

Sample Program:
import java.io.BufferedReader;
import java.io.FileReader;

public class Read2File {
public static void main(String[] args) {
try {
FileReader fileReader = new FileReader("C:\\filename.txt");
BufferedReader bufferedReader = new BufferedReader(fileReader);
String fileLine = null;
StringBuffer temp = new StringBuffer();
while((fileLine = bufferedReader.readLine()) != null) {
                              temp.append(fileLine+"\n");
                        }
System.out.println(temp);
bufferedReader.close();
   fileReader.close();
}catch (Exception e) {
e.printStackTrace();
}
}
}
