Difference between Static and Final in Java

Main difference

The difference between static and final in java is that static is a keyword in java which is used to define the class member which can be used independently of any object of the class while final keyword in java is used to declare a constant variable that cannot be overridden. and a class that cannot be inherited.

Static vs Final in Java

Java is an object-oriented programming language that uses both a compiler and an interpreter. Most software is made in the Java programming language. Java code can be written on Windows, Linux, and Mac OS. The syntax of the C and C++ programming language is practically the same. Java produces a browser to run programs that help create a graphical user interface. Java programming language is used and trending these days. To write Java code, a programmer needs a software development kit (SDK) which includes a compiler, an interpreter which is not required in C++. There are many keywords that are used in Java, so these keywords are static and final If a variable is static, then it can be accessed before the class object is created. Final is a keyword that has a different effect on the class, methods and variables.In Java, static is a keyword that applies to classes, variables, methods, and blocks. We have to use the ‘static’ keyword to make class members like class and block static. You have to use the static word before these class members. Like static final, it is also a keyword used for a class, variable, and methods. Using the “final” keyword, the class, variable, and methods are declared as a final keyword. If a class member is static, then this class member can become global to all class members. There is no memory per instance, that is, all objects have to share the same copy of the static member. The static member in the code is independent of the class object. A static member is accessed before the class object is created. The Main() method is the example of a static member, this is static because it can be used before any object is output. Class_name_static_member is a general to access the static member of the class. For all other data members of the class, the static variable acts as a global variable. You cannot modify a variable as a program after creating a program. You have to declare the final variable before the declaration time. Final variables have no memory space on a per-instance basis. The static variable needs to be accessed before any object of the class. The dot operator (.) is used to access the static variable. Only one copy is created, and all final variables share the same copy of the final variable. Because of the subclass of the class, the method cannot be declared final and cannot be overridden. Inheritance is not allowed in the final class. The final keyword is only used in Java and is not supported in C++ and C#. Static keyword methods can only call another static method. Static data can access the static method. Java doesn’t support static class concept, only outer class can access static class. Static keyword methods can only call another static method. Static data can access the static method. Java doesn’t support static class concept, only outer class can access static class. Static keyword methods can only call another static method. Static data can access the static method. Java doesn’t support static class concept, only outer class can access static class.

Comparison chart
Static Final
Static is a keyword in Java that is used to define the member of the class that can be used independently of any object of the class. The final keyword in java is used to declare a constant variable that cannot be overridden and a class that cannot be inherited.
Modification
The static variable cannot be modified. A final variable can be modified
Class
Cannot create an object of static class A final class object can be created
To block
Static block supports static keyword The final block is not compatible with the final keyword

What is static?

In Java, static is a keyword that applies to classes, variables, methods, and blocks. We have to use the ‘static’ keyword to make class members like class and block static. You have to use the static word before these class members. If a class member is static, then this class member can become global to all class members. There is no memory per instance, that is, all objects have to share the same copy of the static member. The static member in the code is independent of the class object. A static member is accessed before the class object is created. The Main() method is the example of a static member, this is static because it can be used before any object is output. Class_name_static_member is a general to access the static member of the class. For all other data members of the class, the static variable acts as a global variable. A static variable must be accessed before any object of the class. The dot operator (.) is used to access the static variable. Static keyword methods can only call another static method. Static data can access the static method. Java doesn’t support static class concept, only outer class can access static class. ) is used to access the static variable. Static keyword methods can only call another static method. Static data can access the static method. Java doesn’t support static class concept, only outer class can access static class. ) is used to access the static variable. Static keyword methods can only call another static method. Static data can access the static method. Java doesn’t support static class concept, only outer class can access static class.

What is ending?

Like static final, it is also a keyword used for a class, variable, and methods. Using the “final” keyword, the class, variable, and methods are declared as the final keyword. You cannot modify a variable as a program after creating a program. You have to declare the final variable before the declaration time. Final variables do not take space in memory as per instance. Only one copy is created, and all final variables share the same copy of the final variable. Because of the subclass of the class, the method cannot be declared final and cannot be overridden. Inheritance is not allowed in the final class. The final keyword is only used in Java and is not supported in C++ and C#.

Key differences
  1. Static is a keyword in java that is used to define the member of the class that can be used independently of any object of the class, while the final keyword in java is used to declare a constant variable that cannot be overridden and a class that cannot be inherited.
  2. A static variable cannot be modified, while the final variable can be modified.
  3. You cannot create a static class object while you can create a final class object while you can create a final class object,
  4. The static block is supported in the static keyword, while the final block is not supported in the final.
