It shouldn't be a problem for simple stuff because Groovy by default uses. Such exceptions are marked as "optional" in the specification for this interface.īasically this says: Not all maps are the same, so make sure you somewhat know the kind of map you are dealing with (internally) as you attempt these operations on them. More generally, attempting an operation on an ineligible key or value whose completion would not result in the insertion of an ineligible element into the map may throw an exception or it may succeed, at the option of the implementation. Attempting to query the presence of an ineligible key or value may throw an exception, or it may simply return false some implementations will exhibit the former behavior and some will exhibit the latter. Attempting to insert an ineligible key or value throws an unchecked exception, typically NullPointerException or ClassCastException. For example, some implementations prohibit null keys and values, and some have restrictions on the types of their keys. Some map implementations have restrictions on the keys and values they may contain. Notably the interface has a note in there that says: Remember that groovy maps are still just Java maps with " enhancements", so the rules that apply to Java still apply to groovy. If you don't like null, then use you use the elvis operator to assign a default value instead (similar to ): def x = mymap.someKey ?: 'default value' If the key is stored in a variable, use string interpolation with the property notation like so: def key = 'likes' If the key you are looking for (for example 'likes.key') contains a dot itself, then you can quote the key like so: def x = mymap.'likes.key' In this case, x will contain the value of mymap if it exists, otherwise it will be null. Groovy maps can be queried using property notation. Sadly, they only create clutter and should be discarded too.You forgot to mention what happens when the key doesn't exist. As you clean, you may find many "just in case" items you've been holding onto for emergencies. You can start off in the kitchen by ridding your cabinets of the 20 plates hidden in the back or burnt pots you still keep in the oven. If you find it easier, go room by room instead of decluttering your house as a whole. We're talking about shoes you barely wear, any excess magazines and more! Then, move on to smaller items you can easily discard in boxes. Go for the large items first, such as any furniture or rundown decor hidden away in the garage -think broken tables, chairs or smelly rugs. Start with seasonal clothing and gradually work your way through your piles over the course of a few months (or even years if you must!). Since you may have a bulk of clothes to sort through, don't worry about how long it'll take. You're sure to have two or more garments of the same color and size that you never wear.Ĭhoose clothes that no longer fit, discard damaged shirts or pants and donate items that no longer suit your lifestyle. In fact, our closets and drawers may be the easiest to organize. There's no need to start with personal and sentimental items, like love letters or your children's photographs. Swedish death cleaning checklist and steps So, follow the checklist below to get started and decide whether this buzzy cleaning method is right for you. While Swedish death cleaning is all about holding onto essential belongings, pinpointing the items you want to keep and part ways with isn't an easy process. It's a slow process that's been all the rage lately, thanks to Peacock's new show, The Gentle Art of Swedish Death Cleaning, which is produced by Amy Poehler. The thorough organizing method involves editing everything from furniture and clothing to the ever-growing piles of documents that's been difficult to control over time. Swedish death cleaning is a well-known concept in Swedish and Scandinavian culture, where you work on eliminating unnecessary items from your home, so loved ones won't be burdened with the task after you pass. But when it comes to downsizing your belongings, including furniture, clothing, shoes, kitchen essentials and even documents, to prepare for your older years, Swedish death cleaning is an approach that's worth considering. When we insert into a Map collection, two values are required: the key and the value. The keys used in a Map can be of any class. The elements in a Map collection are accessed by a key value. There's no shortage of home decluttering methods - take Marie Kondo's popular minimalist approach, the KonMari Method, for example. A Map (also known as an associative array, dictionary, table, and hash) is an unordered collection of object references.
