   Hi, @swapnilushinde . Thank you for making a PR, but do you the following? It's one-liner.
   ```scala
   scala> spark.version
   res0: String = 2.4.3
   
   scala> spark.read.schema("id int, name string, subject string, marks int, result boolean").load("/tmp/csv").printSchema
   root
    |-- id: integer (nullable = true)
    |-- name: string (nullable = true)
    |-- subject: string (nullable = true)
    |-- marks: integer (nullable = true)
    |-- result: boolean (nullable = true)
   ```
