Just like there are many ways for writing String to text file, there are multiple ways to read String form File in Java. You can use FileReader, BufferedReader, Scanner, and FileInputStream to read text from file. One thing to keep in mind is character encoding. You must use correct ...

1Files.lines(Paths.get("Nio.java"))2.map(String::trim)3.forEach(System.out::println); The above reads the file “Nio.java”, callstrim()on every line, and then prints out the lines. Notice thatSystem.out::printlnrefers to theprintlnmethod on an instance ofPrintStream. ...
}StringfileAsString=sb.toString(); Don't forget to append the\ncharacter to insert the line break, otherwise, all lines will be joined together and all text from the file will come as just one big line. If you are not familiar with\nor\r\n, I suggest you join a comprehensive Java ...
