resourceBundle.getStringArray() throws ClassCastException why? help me, thank you!

Question

public class TestResourceBundle { private static ResourceBundle resourceBundle = ResourceBundle
.getBundle("test"); public static void testGetStringArray() {
String[] values = resourceBundle.getStringArray("propertyS");
for(int i = 0; i < values.length; i++){
System.out.println(values[i]);
}

} public static void main(String[] args) {
testGetStringArray();
}
}test.properties如下:
===============================
key=value1
propertyS=a
propertyS=b
propertyS=c
==============================
resourceBundle.getStringArray()的用法是不是我理解出错了,帮忙指正一下,谢谢!

Answer 1

对资源包ResourceBundle 的用法不正确
读取Properties类型文件可以使用java.util.Properties来进行读取

Answer 2

 //读取properties的全部信息
    public static void readProperties(String filePath) {
     Properties props = new Properties();
        try {
         InputStream in = new BufferedInputStream (new FileInputStream(filePath));
         props.load(in);
            Enumeration en = props.propertyNames();
             while (en.hasMoreElements()) {
              String key = (String) en.nextElement();
                    String Property = props.getProperty (key);
                    System.out.println(key+Property);
                }
        } catch (Exception e) {
         e.printStackTrace();
        }
    }
