What are the advantages and disadvantages of using the Supplier interface in development?

The Supplier interface in Java is a functional interface that takes no arguments and returns a result. Its advantages and disadvantages:

Advantages:

• Allows deferring the computation of a value until the get() method is called, which is useful for lazy evaluations.
• Simplifies passing factory methods or value generators.
• Works well with lambda expressions and the Stream API.

Disadvantages:

• Does not accept input parameters, so it is not suitable for functions that depend on arguments.
• Can complicate code readability if Supplier is used for complex operations without explicit context.

Example:

Supplier<Double> randomSupplier = () -> Math.random();
System.out.println(randomSupplier.get());

Thus, Supplier is convenient for generating values on demand, but its use should be justified by the task.
