throw vs throws in java

throws is used to specify that an exception/s can be thrown. Specifying is more pertinent to checked exceptions.

throw is simply the statement to manually/programically throw the exception or any object of throwable type.

Using throws

a method, and then tell that this method throws following exception…and then write da .. da .. da. Eg.

public void myMethod() throws MalformedURLException,MyCustomException1
//do something in method

Using throw

throw just throws exception. Eg.

throw someObjectOfThrowableType
