Java读取properties文件之中文乱码问题及解决

China=中国
USA=美国
Japan=日本

Properties properties = new Properties();  
InputStream inputStream = this.getClass().getResourceAsStream("/country.properties");  
properties.load(inputStream );  
System.out.println(properties.getProperty("China"));   

Properties properties = new Properties();  
InputStream inputStream = this.getClass().getResourceAsStream("/country.properties");  
BufferedReader bf = new BufferedReader(new  InputStreamReader(inputStream));  
properties.load(bf);  
System.out.println(properties.getProperty("China")); 

// properties文件略
