Java判断变量是否是基本类型以及是否是默认值

判断变量是否是基本类型：

/**
* 判断object是否为基本类型
* @param object
* @return
*/
public static boolean isBaseType(Object object) {
    Class className = object.getClass();
    if (className.equals(java.lang.Integer.class) ||
        className.equals(java.lang.Byte.class) ||
        className.equals(java.lang.Long.class) ||
        className.equals(java.lang.Double.class) ||
        className.equals(java.lang.Float.class) ||
        className.equals(java.lang.Character.class) ||
        className.equals(java.lang.Short.class) ||
        className.equals(java.lang.Boolean.class)) {
        return true;
    }
    return false;
}

判断是否是默认值：

/**
 * 判断是否为基本类型的默认值
 * @param object
 * @return
 */
public static boolean isBaseDefaultValue(Object object) {
    Class className = object.getClass();
    String strClassName = "" + className;
    if(className.equals(java.lang.Integer.class)) {
        return (int)object == 0;
    } else if(className.equals(java.lang.Byte.class)) {
        return (byte)object == 0;
    } else if(className.equals(java.lang.Long.class)) {
        return (long)object == 0L;
    } else if(className.equals(java.lang.Double.class)) {
        return (double)object == 0.0d;
    } else if(className.equals(java.lang.Float.class)) {
        return (float)object == 0.0f;
    } else if(className.equals(java.lang.Character.class)) {
        return (char)object == '\u0000';
    } else if(className.equals(java.lang.Short.class)) {
        return (short)object == 0;
    } else if(className.equals(java.lang.Boolean.class)) {
        return (boolean)object == false;
    }
    return false;
}
