Read a line in java and then tokenize it

I am looking for easiest way to read a li开发者_Python百科ne in Java. Once read, I want to tokenize the line. Any suggestions?

import java.util.*;

//...

Scanner sc = new Scanner(System.in);
String line = sc.nextLine();
if (sc.hasNextInt()) {
  int i = sc.nextInt();
  //...
}

java.util.Scanner API

• It can take a File, InputStream, and String as source (among other things)
  • new Scanner(new File("input.txt"))
  • new Scanner("some string you want to tokenize")
• You can also set custom delimiter
  • sc.useDelimiter(";")
• Supports regex too
  • sc.next("[a-z]+")

Elsewhere on stackoverflow:

• Java’s Scanner vs String.split() vs StringTokenizer; which should I use?
• How to read integer value from the standard input in Java
• How do I keep a scanner from throwing exceptions when the wrong type is entered?

FileUtils.readLines(..) from commons-io

Then use String.split(regex) rather than a tokenizer.
