What is the method for declaring Java symbolic constants?

In Java, the final keyword can be used to declare a constant variable.

A symbolic constant is a variable that cannot be changed once it is assigned a value, typically used to represent fixed values such as mathematical constants or configuration items.

The steps to declare a symbolic constant are as follows:

1. last
2. Specify the data type of the variable.
3. Once a value is assigned to a variable, it cannot be changed.

For example, declare an integer constant symbolizing the value of the mathematical constant π (pi).

final double PI = 3.14159;

In the above code, the final keyword is used to declare the variable PI as a symbolic constant with a data type of double and an initial value of 3.14159. This constant cannot be modified after it is assigned a value.

Please note that symbolic constants are typically named using all capital letters, with underscores used to separate multiple words, in order to enhance the readability of the code.

I hope the above information is helpful to you!
