In which cases is it advisable to use the Supplier pattern in programming?

The Supplier pattern in Java represents a functional interface that takes no arguments and returns a result. It is advisable to use it in the following cases:

• When you need to defer the computation of a value until it is actually used (lazy evaluation).
• To generate new objects on demand without the need to pass parameters.
• In situations where you need to pass creation logic or a value as a function, for example, in methods that accept a Supplier for lazy initialization.

Example of usage:

Supplier<Double> randomSupplier = () -> Math.random();

// The value will be computed only when get() is called
double randomValue = randomSupplier.get();

Thus, Supplier helps to separate the logic of creating a value from its immediate use.
