These are the necersary imports:
import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
And this is a method that will allow you to read from a File by passing it the filename as a parameter like this: readFile("yourFile.txt");
String readFile(String fileName) throws IOException {
BufferedReader br = new BufferedReader(new FileReader(fileName));
try {
StringBuilder sb = new StringBuilder();
String line = br.readLine();
while (line != null) {
sb.append(line);
sb.append("\n");
line = br.readLine();
}
return sb.toString();
} finally {
br.close();
}
}
