----------------------------//加配置文件的方法

配置文件名：tank.properties

initTankCount=10
reProduceTankCount=15

--------------------------------使用局部配置

//加配置文件 ； Properties props = new Properties(); try { props.load(this.getClass().getClassLoader().getResourceAsStream("config/tank.properties")); } catch (IOException e1) { e1.printStackTrace(); } int initTankCount = Integer.parseInt(props.getProperty("initTankCount")); for(int i = 0; i < initTankCount; i++) { tanks.add(new Tank(40 * (i + 1), 400, false, this, Tank.Direction.U)); }
------------------使用全局配置

import java.io.IOException; import java.util.Properties; public class PropertyMgr { static Properties props = new Properties(); static { try { props.load(PropertyMgr.class.getClass().getClassLoader().getResourceAsStream("config/tank.properties")); } catch (IOException e1) { e1.printStackTrace(); } } private PropertyMgr(){}; public static String getProperty(String key) { return props.getProperty(key); } }
for(int i = 0; i < Integer.parseInt(PropertyMgr.getProperty("initTankCount")); i++) { tanks.add(new Tank(40 * (i + 1), 400, false, this, Tank.Direction.U)); }
