java字符串分割

我们的配置文件内容如下：
zhangsan=30
lisi=50
wangwu=60
sb=222
import java.util.Properties;
import java.io.*;
public class PropertiesDemo {
    public static void main(String[] args) {
        getproperties();
    }
    public static void getproperties()
    {
        BufferedReader br=null;
        try { 
             br=new BufferedReader(new FileReader("D:/Eclipse_jee_java/javaDemo/Demo1/src/Demo1/properties.pro"));//加载配置文件
             String lean=null;
             try {
                while((lean=br.readLine())!=null)
                 {
                    String[] s=lean.split("=");//切割
                     System.out.println(s[0]+"----"+s[1]);
                 }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }

    }
}
