1The Throws/Throw Keywords

If a method unable to manage a checked exception then the method must declare if it is using throw keyword. This keyword will appear at the end of method’s signature. You can throw the exception, either in a newly instantiated way or an exception you caught by using that throw keyword.
Attempt to comprehend the distinction amongst throw and throws keywords,throws is utilized to put off the treatment of a checked special case and toss is utilized to summon an exemption expressly.
The accompanying technique announces that it tosses a RemoteException −
Example
import java.io.*;
public class className {

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

This method proved that it throws multiple exception, and in which case exceptions are declared in a separated list with Commas. For illustration, this method proves that it throws a remoteexception as well as an Insufficient Funds Exception.

Example

import java.io.*;
public class className {
public void withdraw(double amount) throws RemoteException,
InsufficientFundsException {
// Method implementation
}
// Remainder of class definition
}
