Java classes objects and methods
Object Class in Java | Methods and Examples of Object Class in Java
Much of Java programming consists of creating objects and then manipulating them by calling the methods of the class. In every Java program, the first statement executed is always the first statement in the main method of the programmer-defined class. All other methods are executed only when called

(objRef1 = = objRef2) compares the references, not the objects themselves. In Java, we write/use the equals() method when we want to compare the contents of two objects of the same class. Most Java classes will have an equals() method. When you write a new class, you should consider whether you should write an equals() method for it.

Classes: The fundamental structure of every Java program, containing data fields and mechanisms to manipulate that data. Classes provide blueprints to construct software objects. Instances: Objects constructed according to class blueprints that exist in the memory of the computer. One class can be used to instantiate any number of objects.

These exercises focus on the String, Math, and Scanner classes defined in the Java Standard Class Library. The main concepts are in the text in sections 2.5 - 2.7 (for objects and methods). The goals of the lab are for you to gain experience with the following concepts:

methods to modify the state of objects. methods to provide access to the current state of objects Java classes begin with public class followed by the class name. The instance variables and methods follow within a set of matching curly braces. The methods and state should have some sort of meaningful connection.

the java runtime system detects garbage and automatically reclaims the space it occupies, i.e., the Java Virtual Machine (JVM) will automatically delete the object and reclaim the memory space if the object is no longer referenced by a reference variable.
