How are universal constants typically formatted in Java?

Universal constants in Java are conventionally formatted in all uppercase letters with words separated by underscores. This naming convention enhances readability and clearly differentiates constants from other variables in the code. By using all caps, developers can instantly recognize that these values are constants and should not be modified during the program's execution.

For example, a constant representing the mathematical value of pi might be defined as public static final double PI = 3.14159;. This formatting practice is common in many programming languages to maintain consistency and improve code maintainability. Consistently using this style helps other developers understand that the value should remain constant, supporting good coding practices.
