Question

I have a file, I know that file will always contain only one word.
So what should be the most efficient way to read this file ?

Do i have to create input stream reader for small files also OR Is there any other options available?

Answer 1

Use Scanner

File file = new File("filename");
Scanner sc = new Scanner(file);
System.out.println(sc.next()); //it will give you the first word

if you have int,float…as first word you can use corresponding function like nextInt(),nextFloat()…etc.
