Interface ThrowingSupplier<T,E extends Exception>

Type Parameters:
T - The type of the result supplied
E - The type of exception thrown by the supplier
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface public interface ThrowingSupplier<T,E extends Exception>
A version of Supplier that allows throwing a checked Exception.

This interface is useful when working with functional programming constructs that need to handle checked exceptions, such as stream operations or deferred computations.

Usage Example


 ThrowingSupplier<String, IOException> fileReader = () -> {
     try (BufferedReader reader = new BufferedReader(new FileReader("example.txt"))) {
         return reader.readLine();
     }
 };

 try {
     String line = fileReader.get();
     System.out.println("Read line: " + line);
 } catch (IOException e) {
     e.printStackTrace();
 }
