JDK 1.5中 Scanner类的应用

import java.util.Scanner;

public class ScannerTest {
 public static void main(String[] args) {
  String str = "1 2 3 4 5 6 7 8 9";
  Scanner scanner1 = new Scanner(str);// 默认的分隔符为 whitespace
  int total = 0;
  while (scanner1.hasNext()) {
   total += scanner1.nextInt();
  }
  System.out.println(total);

  String s="red fish blue fish black fish over";
  Scanner scanner2= new Scanner(s).useDelimiter("//s*fish//s*"); // 定制分隔符
  while(scanner2.hasNext()){
   System.out.println(scanner2.next()); 
  }
 }
}
