Unless a developer checks any implemented interfaces when adding a constant to a class, or does so but makes a typo in the name of the added constant, the value of a constant can be silently changed. Consider Example 2 below. Note that the Java libraries use constant interface pattern themselves.
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
Note: Java does not support pointers. [6] It is because pointers (with restrictions) are the default way of accessing objects in Java, and Java does not use stars to indicate them. For example, i in the last example is a pointer and can be used to access the instance. One can also declare a pointer to "read-only" data in C++.

Static import is a feature introduced in the Java programming language that allows members (fields and methods) which have been scoped within their container class as public static, to be used in Java code without specifying the class in which the field has been defined.
For example, in C, int const x = 1; declares an object x of int const type – the const is part of the type, as if it were parsed "(int const) x" – while in Ada, X: constant INTEGER:= 1_ declares a constant (a kind of object) X of INTEGER type: the constant is part of the object, but not part of the type. This has two subtle results.
