How does java detects Checked Exceptions? -


if write things :

public static void main(string[] args) {     try {     } catch (malformedurlexception e) {          e.printstacktrace()     }; }

java compiler shows compilation error @ catch clause of malformedurlexception. if insert line url url = new url("hi"); in try block , complaining stops. thought java must binding these checked exceptions package. tried class of java.net package inserting " cookiemanager manager = new cookiemanager(); " in try block. compilation error again starts.

so how jvm bind these checked exceptions java classes compilation time errors this?

a method declaration specifies exceptions method throws. information accessible compiler. compiler emits error message if attempt catch exception cannot thrown code invoked in try clause.
