Sync and Async RegexSolver Clients

In Java, you can choose between RegexSolverClient (synchronous) and AsyncRegexSolverClient (asynchronous).

Synchronous

Code
import com.regexsolver.api.RegexSolverClient;
import com.regexsolver.api.Term;
import com.regexsolver.api.exceptions.ApiException;

public class Main {
    public static void main(String[] args) throws ApiException {
        RegexSolverClient client = RegexSolverClient.builder()
            .apiToken(System.getenv("REGEXSOLVER_API_TOKEN"))
            .build();
        
        Term a = Term.regex("abc");
        Term b = Term.regex("def");
        
        Term result = client.union(a, b);
        System.out.println(result);
    }
}

Asynchronous

Code
import com.regexsolver.api.AsyncRegexSolverClient;
import com.regexsolver.api.Term;
import com.regexsolver.api.exceptions.ApiException;
import java.util.concurrent.CompletableFuture;

public class Main {
    public static void main(String[] args) throws ApiException {
        AsyncRegexSolverClient client = AsyncRegexSolverClient.builder()
            .apiToken(System.getenv("REGEXSOLVER_API_TOKEN"))
            .build();
        
        Term a = Term.regex("abc");
        Term b = Term.regex("def");
        
        // Returns a CompletableFuture<Term>
        client.union(a, b)
            .thenAccept(result -> System.out.println("Union: " + result));
    }
}
