Reading from a text file and storing in a String
file, file-io, java
Solution
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();
}
}
Problem
How can we read data from a text file and store in a String variable? is it possible to pass the filename in a method and it would return the String which is the text from the file. What kind of utilities do I have to import? A list of statements will be great.
