如何向Scala提供Java回调(带有'void‘返回类型)？

trait JavaCallback {
  def callback(): Unit
}

class ScalaImplementation extends JavaCallback {
  def callback(): Unit = {
    // 执行回调逻辑
    println("Java回调已触发")
  }
}

public interface JavaInterface {
  void registerCallback(JavaCallback callback);
}

public class JavaImplementation implements JavaInterface {
  public void registerCallback(JavaCallback callback) {
    // 调用Scala回调对象的方法
    callback.callback();
  }
}

object Main {
  def main(args: Array[String]): Unit = {
    val scalaCallback = new ScalaImplementation()
    val javaImplementation = new JavaImplementation()

    javaImplementation.registerCallback(scalaCallback)
  }
}
