This is deprecated and you should now use getsize. MyAppletDimension.size() - returns an object with the width and height of an applet. MyVector.size() - Number of elements in a Vector and MyFile.length() - Number of bytes in a file. MyStringBuffer.length() - String Buffer length. MyArrayList.size() - number of elements in an Array List. Which is it in which circumstances? I have no magic answer - you just need to learn / know. Java uses size where you're looking at a measure of the number of elements in something which is not in successive memory locations, or may not be, or where the elements themselves differ in size so you can't find out how many of them there are by measuring the distance from start to end.Īnd Java uses capacity where you're being told how much something can hold, and not how much it's holding at the moment.ĭo you add brackets after the length / capacity / size word? If you're looking at a variable within the object, you don't, but if you're calling a method you do. Java uses the word length when you're asking about something that can be determined by telling you the distance from the start to the end of something - thus an array, with fixed size elements arranged sequentially in memory, is going to be a length. Aren't they really all the same sort of thing? Which does Java use in which circumstance? If the family knows no one uses the computers and tablet for working or studying from home, they might even be able to get away with 100 or 150 Mbps.You get the length of an array, but you ask about the size() of an ArrayList, and you can inquire into the capacity() of a StringBuffer. If the family knows they usually stream 4K videos on one of their TVs about once a week and in the evening when no one’s on their computers, gaming on the Xbox, or using the printer, they can probably knock this speed down a bit to 200 Mbps. That’s where online activities can factor in. This recommendation assumes that every person and every device is online at the same time. That may seem like a lot of speed, and you’re probably right. The recommended internet speed for this family is 270 Mbps. Home security camera: 10 Mbps x 2 = 20 Mbps.Desktop computer: 10 Mbps x 2 = 20 Mbps.

Here’s a list of the internet speeds each person gets, plus the internet speeds each of their devices gets. Let’s say we have a home with two adults and two children who all use the internet. Okay, now let’s see how those recommended speeds add up with an example. (But if it’s a 4K device, bump that up to 25 Mbps.) And for every device, you can allot 10 Mbps. We recommend giving each person who uses the internet in your home 25 Mbps.
