1.在src目录下：新建一个config.properties文件
内容：
name = zhang
age =25;
score =98
ID=0002
2.新建一个类：
package ch3;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
public class PropertiesText {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
InputStream is = Thread.currentThread().getContextClassLoader().getResourceAsStream("config.properties");
Properties pop = new Properties();
try {
pop.load(is);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String name = pop.getProperty("name");
String id =pop.getProperty("ID");
String score =pop.getProperty("score");
String age = pop.getProperty("age");
System.out.println("name:"+name+"\tid:"+id+"\tscore:"+score+"\tage:"+age);
}
}
