例子程序：
import java.util.Scanner;
import java.io.File;
import java.io.FileNotFoundException;
public class ReadHuman {
private static void readFile(String fileName) {
try {
Scanner scanner = new Scanner(new File(fileName));
scanner.useDelimiter(System.getProperty("line.separator"));
while (scanner.hasNext()) {
parseLine(scanner.next());
}
scanner.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
private static void parseLine(String line) {
Scanner lineScanner = new Scanner(line);
lineScanner.useDelimiter("\\s*,\\s*");
//可以修改useDelimiter参数以读取不同分隔符分隔的内容
String name = lineScanner.next();
int age = lineScanner.nextInt();
String idate = lineScanner.next();
boolean isCertified = lineScanner.nextBoolean();
System.out.println("姓名：" + name + "，年龄：" + age + "，入司时间："+idate+"，验证标记：" + isCertified );
}
public static void main(String[] args) {
if (args.length != 1) {
System.err.println("usage: java ReadHuman file location");
System.exit(0);
}
readFile(args[0]);
}
}
