+# Handling Events
+
+LDK requires that you handle many different events throughout your app's life cycle. You can learn more by reading about our event-driven [architecture](/overview/architecture.md).
+
+To start handling events in your application, run:
+
+<CodeSwitcher :languages="{rust:'Rust', java:'Java', kotlin:'Kotlin'}">
+  <template v-slot:rust>
+
+  ```rust
+  use lightning::util::events::{Event};
+
+  // In the event handler passed to BackgroundProcessor::start
+  match event {
+    Event::PaymentSent { payment_preimage } => {
+            // Handle successful payment
+    }
+    Event::PaymentFailed { payment_hash, rejected_by_dest } => {
+            // Handle failed payment
+    }
+    Event::FundingGenerationReady { .. } =>
+}
+  ```
+  </template>
+  <template v-slot:java>
+ 
+  ```java
+  import org.ldk.batteries.ChannelManagerConstructor
+
+  ChannelManagerConstructor channelManagerConstructor = new ChannelManagerConstructor(
+    Network.LDKNetwork_Bitcoin, 
+    UserConfig.default(), 
+    latestBlockHash,
+    latestBlockHeight, 
+    keysManager.as_KeysInterface(), 
+    feeEstimator, 
+    chainMonitor,
+    router, 
+    txBroadcaster, 
+    logger
+  );
+  ```
+
+  </template>
+
+   <template v-slot:kotlin>
+ 
+  ```kotlin
+  import org.ldk.batteries.ChannelManagerConstructor
+
+  val channelManagerConstructor = ChannelManagerConstructor(
+      Network.LDKNetwork_Regtest,
+      userConfig,
+      latestBlockHash,
+      latestBlockHeight,
+      keysManager.as_KeysInterface(),
+      feeEstimator,
+      chainMonitor,
+      router,
+      txBroadcaster,
+      logger
+  );
