Why JVM Call main() method? JVM is a program in which the main() method is configured that is the reason JVM called the main method. we can change the name of the main() method but we need to change the method calling in JVM. Explanation of the main method : public static void main(String [] args) is a method that is called by JVM.  Public : Public is an access modifier of the main method. the main method is public because the JVM can call this method from anywhere. static : without creating an object JVM can call this method that's why the main method is static. without an existing object also JVM has to call this method and the main method is not related to any Object. void:  void is a return type of the main method, the main method not returning any value to JVM. main : this is the method name that is configured in JVM.  String[] args : these are command-line arguments.

 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. The mat-date-range-input component requires two input elements for the Start Date and the end date. you need the below libs for the Range date picker : 1. Angular material  (ng add @angular/material) 2.moment (npm install moment -- save) 3.material-moment-adapter (npm install @angular/material-moment-adapter) Syntax : <mat-date-range-input>   <input matStartDate placeholder="Start Date"></i...
