, this usage is not a good habit and is not recommended for everyone to use. Essentially, when you create an associative array, you create an array object's properties. In JavaScript, all variables are actually objects of some kind. For example, a Boolean value is an object of type Boolean. In the above example, you are actually adding the name, year, and living three properties to the lemon array. Ideally, you should not modify the properties of an array object, but you should use a generic obj

False2. Range of valuesDue to memory limitations, ECMAScript cannot save all the values in the world, and the smallest value ECMAScript can represent is saved in Number.min_value, which is 5e-324 in most browsers. The maximum value that can be represented is saved in Number.MAX_VALUE, which is 1.7976931348623157e+308 in most browsers. If the result of a calculation is given a value that is outside the range of JavaScript values, if the value is negative, it is converted to-infinity (negative in

The compiler generates a public, parameterless default constructor only if the class does not contain an explicit constructor. This class cannot be instantiated as long as a class contains a private constructor. Example:1 //Tool Class2 Public classUtilityclass {3 //Private Constructors4 PrivateUtilityclass {5 Throw Newassertionerror ();6 }7 8 //Other operations ...9}　　Assertionerror avoid invoking the constructor inside the class to ensure that the class is not inst

up when a new entry is added to the cache. The Linkedhashmap class can implement the latter through its Removeeldestentry method. For more complex caches, you must use Java.lang.ref directly.A third common source of memory leaks is listeners and other callbacks.If the client registers callbacks in its own implementation of the API, but does not explicitly unregister, they will accumulate unless some action is taken. The best way to ensure that callbacks are immediately treated as garbage collec

way to impose constraints on multiple parameters is to check all the parameters that a constraint must hold with multiple setter methods. Once an invalid argument is passed, the constraint fails immediately, rather than waiting for the build method to be called. The slight advantage of builder compared to constructors is that builder can have multiple mutable parameters. Constructors, like methods, can have only one mutable parameter.The traditional abstract factory implementation in Java is a
