java写配置文件代码,java配置教程

java配置文件怎么写?

参考java.util.Properties对象进行书写，另外可以在网上找一写辅助书写材料。

代码：

public static void main(String[] args) {

Properties p = new Properties();

p.setProperty("id", "user1");

p.setProperty("password", "123456");

try{

PrintStream stm = new PrintStream(new File("e:\test.properties"));

p.list(stm);

} catch (IOException e) {

e.printStackTrace();

}

}
