i) A static field is shared by all instances of a class, and there is only one copy of a static field regardless of how many instances of the class are created.
ii) A static method can be called directly on the class, rather than on an instance of the class.
iii) A static block of code is executed when a class is first loaded by the JVM before any objects are created. It's commonly used for initializing static fields.
iv) A static nested class is a class that is defined inside another class, but it does not have access to non-static members of the outer class.
The static keyword in Java is used to define members (fields or methods) that belong to the class rather than any specific instance of the class. Static members are shared among all instances of the class, meaning they are accessed without creating an object of the class. It is commonly used for utility methods, constants, and shared data.
A static keyword in Java indicates that a particular field, method, block, or nested class belongs to a class rather than to any of its instances. Static members are shared across all instances of the class. For example, a static method can be called without creating an object of the class, and a static field retains a single shared value across all instances.
