java中判断Object对象类型

Object param = (i);
   if (param instanceof Integer) {
    int value = ((Integer) param).intValue();
    (i + 1, value);
   } else if (param instanceof String) {
    String s = (String) param;
    (i + 1, s);
   } else if (param instanceof Double) {
    double d = ((Double) param).doubleValue();
    (i + 1, d);
   } else if (param instanceof Float) {
    float f = ((Float) param).floatValue();
    (i + 1, f);
   } else if (param instanceof Long) {
    long l = ((Long) param).longValue();
    (i + 1, l);
   } else if (param instanceof Boolean) {
    boolean b = ((Boolean) param).booleanValue();
    (i + 1, b);
   } else if (param instanceof Date) {
    Date d = (Date) param;
    (i + 1, (Date) param);
   }
