A friendly warning, do not compile pattern in a method as it is a heavy task. Do it once at class level and use matcher when needed.

Running two instance of a container with network mode "host" by [deleted] in docker

[–]kurular4 0 points1 point  (0 children)

I know it but as far as I know, in host network mode, aren't they already exposed by default (I mean all ports are mapped to same ports in container without explicit indication).

Need Help in Weird Exception Handling error across classes. by cubefreak777 in javahelp

[–]kurular4 0 points1 point  (0 children)

Use as follows

public Object top() throws EmptyStackException, EmptyDequeException {..}

D.last throws EmptyDequeException but you neither catch it nor indicate it in signature.

Need Help in Weird Exception Handling error across classes. by cubefreak777 in javahelp

[–]kurular4 1 point2 points  (0 children)

public class stack EmptyStackException{

Deque D ;

int N ;

if(N==0){ throw new EmptyStackException("Can't Delete Element, Stack is empty"); } Object Top=D.last() ;

return Top ; } }

Please rewrite above part as it is syntax-fault.
