        ```
    2. 如下示例调用CallWithResult接口，向Callee被调用端发送待处理的数据originMsg，并将’CallSendMsg’方法处理完毕的数据赋值给backMsg。
       
-       ```ts
-       const MSG_SEND_METHOD: string = 'CallSendMsg';
-       let originMsg: string = '';
-       let backMsg: string = '';
-       async onButtonCallWithResult(originMsg, backMsg) {
-           try {
-               let msg = new MyParcelable(1, originMsg);
-               const data = await this.caller.callWithResult(MSG_SEND_METHOD, msg);
-               console.info('caller callWithResult succeed');
-       
-               let result = new MyParcelable(0, '');
-               data.readParcelable(result);
-               backMsg(result.str);
-               console.info(`caller result is [${result.num}, ${result.str}]`);
-           } catch (error) {
-               console.info(`caller callWithResult failed with ${error}`);
-           }
-       }
-       ```
+        ```ts
+        import UIAbility, { Caller } from '@ohos.app.ability.UIAbility';
+        import rpc from '@ohos.rpc';
+        const MSG_SEND_METHOD: string = 'CallSendMsg';
+        let originMsg: string = '';
+        let backMsg: string = '';
+        export default class EntryAbility extends UIAbility {
+            // ...
+            caller: Caller | undefined;
+            async onButtonCallWithResult(originMsg: string, backMsg: string) {
+                try {
+                    let msg: MyParcelable = new MyParcelable(1, originMsg);
+                    if (this.caller) {
+                        const data = await this.caller.callWithResult(MSG_SEND_METHOD, msg);
+                        console.info('caller callWithResult succeed');
+                        let result: MyParcelable = new MyParcelable(0, '');
+                        data.readParcelable(result);
+                        backMsg = result.str;
+                        console.info(`caller result is [${result.num}, ${result.str}]`);
+                    }
+                } catch (error) {
+                    console.info(`caller callWithResult failed with ${error}`);

+            }
+            // ...
+        }
+        ```
 
 6. 释放Caller通信接口。
    Caller不再使用后，应用开发者可以通过release接口释放Caller。
 
    ```ts
-   releaseCall() {
-       try {
-           this.caller.release();
-           this.caller = undefined
-           console.info('caller release succeed');
-       } catch (error) {
-           console.info(`caller release failed with ${error}`);
-       }
+   import UIAbility, { Caller } from '@ohos.app.ability.UIAbility';
+   export default class EntryAbility extends UIAbility {
+    caller: Caller | undefined;
+    releaseCall() {
+        try {
+            if (this.caller) {
+                this.caller.release();
+                this.caller = undefined;
+            }
+            console.info('caller release succeed');
+        } catch (error) {
+            console.info(`caller release failed with ${error}`);
+        }
+    }
    }
    ```
