創建一個和src同級的目錄，名為resources，里面放一個配置文件config.properties:4

內容：
#Crunchify Properties
user=Jerry
company1=Google
company2=eBay
company3=Yahoo

使用如下的java代碼讀取這個配置文件：

package partner1;import java.io.InputStream; import java.util.Date; import java.util.Properties;public class Test {public void work(){InputStream input = null;Properties prop = new Properties();String propFileName = "config.properties";input = getClass().getClassLoader().getResourceAsStream(propFileName);if (input != null) {try {prop.load(input);int available = input.available();System.out.println("Available: " + available);String user = prop.getProperty("user");String company1 = prop.getProperty("company1");String company2 = prop.getProperty("company2");String company3 = prop.getProperty("company3");Date time = new Date(System.currentTimeMillis());String result = "Company List = " + company1 + ", " + company2 + ", " + company3;System.out.println(result + "\nProgram Ran on " + time + " by user=" + user);input.close();} catch (Exception e) {System.out.println("Exception: " + e);} finally {}}}public static void main(String[] args) {Test test = new Test();test.work();} }

注意resources文件夾需要設置成build path：

<?xml version="1.0" encoding="UTF-8"?> <classpath><classpathentry excluding="resources/" kind="src" path="src"/><classpathentry kind="src" path="resources"/>

執行結果：
