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
