How to Define Constants in Java

There are several ways to define constants in Java.

1. In Java, you can use the final keyword to declare a constant. For example:
2. The maximum size is set to 10.
3. Combining the static final keywords: If you want to use the same constant throughout the whole class, you can declare a static constant by combining the static final keywords. For example:
4. The maximum size is defined as 10 and cannot be changed.
5. Using enum: In Java, you can define a set of constants using enums. For example:
6. This is an enumeration of the days of the week: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.
7. An interface can be used in Java to define a set of constants. For example:
8. interface Constants {
   final int MAX_SIZE = 10;
   }

It is important to note that different definition methods are suitable for different scenarios. The use of the ‘final’ keyword is appropriate for scenarios involving local constants, instance constants, and static constants. Enums are suitable for defining a set of related constants, while interfaces are suitable for defining a collection of constants.
