                 URL: https://issues.apache.org/jira/browse/SPARK-45515

Example:

  switch (fruit) {
    case "Apple":
      return 1.0;
    case "Orange":

    default:
      throw new IllegalArgumentException();
   }
 }
```  
Can be changed to 
```java 
  double getPrice(String fruit) {
    return switch (fruit) {
      case "Apple" -> 1.0;
      case "Orange" -> 1.5;
      case "Mango" -> 2.0;
      default -> throw new IllegalArgumentException();
    };
  }
```
