Unchecked Exception

This lib hase zero dependencies and can be used to throw checked exceptions without declaring this in your method's head throws clause. And without wrapping Exception into a RuntimeException. Basically you can throw any Exception everywhere without catching them, happy throwing :-D

Methods

unchecked(Exception) rethrows any exception as unchecked exception, without wrapping exception.

  throw unchecked(checkedException);

unchecked(LambdaFunction) returns result or rethrows exception from lambda function as unchecked exception, without wrapping exception.

  return unchecked(() -> methodThrowingCheckedException())

Usage Examples

Try-Catch Block

Regular Code

  import static me.qoomon.UncheckedExceptions.*;

  public class Example {
      
      void example() {
          URL url;
          // code polition with try catch block
          try {
            url = new URL("https:/www.example.org");
          } catch (MalformedURLException e) {
            // ugly exception wrapping
            throw RuntimeException(e); 
          }
          System.out(url);
      }
  }

Unchecked Exception Code

  import static me.qoomon.UncheckedExceptions.*;

  public class Example {
      
      void example() {
        // get rid of code polition with try catch block and exception wrapping
        URL url = unchecked(() -> new URL("https:/www.example.org"));
        System.out(url);
      }
  }

Stream

Regular Code

  
    import static me.qoomon.UncheckedExceptions.*;
  
    public class Example {
        
        void example() {
          Stream.of("https:/www.example.org")
            .map(url -> {
              // code polition with try catch block
              try {
                return new URL(url);
              } catch (MalformedURLException e) {
                // ugly exception wrapping
                throw new RuntimeException(e);
              }
            });
        }
    }

Unchecked Exception Code

  
    import static me.qoomon.UncheckedExceptions.*;
  
    public class Example {
        
        void example() {
            Stream.of("https:/www.example.org")
                // get rid of code polition with try catch block and exception wrapping
                .map(url -> unchecked(() -> new URL(url)));
