Reading a text file in java

Question

How would I read a .txt file in Java and put every line in an array when every lines contains integers, strings, and doubles? And every line has different amounts of words/n

Answer 1

The best approach to read a file in Java is to open in, read line by line and process it and close the strea

// Open the file
FileInputStream fstream = new FileInputStream("textfile.txt");
BufferedReader br = new BufferedReader(new InputStreamReader(fstream));

String strLine;

//Read File Line By Line
while ((strLine = br.readLine()) != null)   {
  // Print the content on the console - do what you want to do
  System.out.println (strLine);
}

//Close the input stream
fstream.close();
