Daemon thread in java: Daemon thread is a low priority thread providing services to the user thread. This thread runs in the background to perform tasks such as garbage collection. Major Properties: It cannot prevent the JVM from exiting when all the user threads finish their execution. JVM terminates itself […]
Stacks In Java
December 19, 2024
Stack is a linear data structure ( an abstract data type ) with a fixed capacity. Linear data structure which is simple to use and allows adding and removing elements in a particular order i.e. a last-in-first-out (LIFO) order. Every element enters the stack from the top and leaves from the […]
Polymorphism in Java
December 19, 2024
The word polymorphism means having many forms. This feature of object-oriented programming allows us to perform a single action in different ways. In other words, polymorphism allows you to define one interface and have many implementations. The word “poly” means many and “morphs” means forms, which means multiple forms. In Java, […]
