object and class in java

OBJECT AND CLASS IN JAVA In this page, we will learn about java objects and classes. In object-oriented programming technique, we design a program using objects and classes. Object is the physical as well as logical entity whereas class is the logical entity only. Object in Java An entity that has state and behavior is known as an object e.g. chair, bike, marker, pen, table, car etc. It can be physical or logical (tangible and intangible). The example of intangible object is banking system. An object has three characteristics: state:  represents data (value) of an object. behavior:  represents the behavior (functionality) of an object such as deposit, withdraw etc. identity:  Object identity is typically implemented via a unique ID. The value of the ID is not visible to the external user. But, it is used internally by the JVM to identify each object uniquely. For Example: Pen is an object. Its name is Reynolds, color is white etc. kno
