import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;

public class DatDemo {
	public static void main(String[] args) throws Exception {

		File file = new File("c:\\test.dat");
		BufferedReader br = new BufferedReader(new FileReader(file));//输入流
		String str;
		while((str=br.readLine())!=null){//按行读取
			String[] ss = str.trim().split(":");
			if(ss.length==2){//如果包含key和value就输出
				System.out.println("key="+ss[0].trim()+"\nvalue="+ss[1].trim());
			}else{//只有key 没有value就输出value=null
				System.out.println("key="+ss[0].trim()+"\nvalue="+"null");
			}
		}
		br.close();//关闭流
	}
}

运行测试
