Using @Async annotation we can create the asynchronous method in spring. If we add @Async annotation on the method then spring Will execute the method in a separate thread in the background thread pool.  Enabling @Async support in spring boot To enable asynchronous processing, you need to add @EnableAsync in the spring configuration class. @EnableAsync annotation will look for a method marked with @Async annotation and run them in the background thread pool.  @Configuration @EnableAsync public class AsyncConfig { ... }   @Async has two rules It must be applied to the public method only.

 Previously if you need to select a start date and end date in date picker, this is not possible in one date picker. so we create two different date-picker one for the start date and the other for end date Rage Date Picker required two dates Start Date and End date. If you want to select two Dates in the Date picker then angular 10 Release Range Date Picker where you can select start date as well as end date in the same date-picker. You can use the mat-date-range-input and mat-date-range-picker components. they work similarly to the mat-date picker and basic date Picker.
