4. In the Code area, type in the following lines:
   ```
   String foo = "bar";
   String K1;
   String Result = "The value is:";
   ```
   ```
   Result = Result + globalMap.get("K1");
   ```
   ```
   System.out.println(Result);

   ```

   In this use case, we use the *Result* variable. To access the global variable list, press Ctrl + Space bar on your keyboard and select the relevant global parameter.
