Java The Throw/Throws Keyword

Comment

//f a method does not handle a checked exception, the method must declare it using the throws keyword. The throws keyword appears at the end of a method's signature. 
One can throw an exception, either a newly instantiated one or an exception that you just caught, by using the throw keyword. 
Understand the difference between throws and throw keywords, throws is used to postpone the handling of a checked exception and throw is used to invoke an exception explicitly. 
Example
import java.io.*;
public class className {

   public void deposit(double amount) throws RemoteException {
      // Method implementation
      throw new RemoteException();
   }
   // Remainder of class definition
}

throw and throws keyword in java

Comment

Throws keyword used for handling exceptions. 
  Where do you use it? Methods signature. 
 If you want to handling right away in selenium or Api use “throws” keyword.
Throw is creating an exception. Basically there are doing opposite. 
Where do you use it? We use it with in the block.
