code to insert values/rows into oracle database from a java swing textfield when a button is pressed(using preparedstatements)
3887suppose in a class there is a code like this: { Set hs=new Hashset(); hs.add(new Emp("kathy",1000)); hs.add(new Emp("kathy",2000)); } how can u avoid the above code in your class as set won't allow duplicate objects?
3 5461Write a java program to find the route that connects between Red and Green Cells. General Rules for traversal 1. You can traverse from one cell to another vertically, horizontally or diagonally. 2. You cannot traverse through Black cells. 3. There should be only one Red and Green cell and at least one of each should be present. Otherwise the array is invalid. 4. You cannot revisit a cell that you have already traversed. 5. The maze need not be in the same as given in the above example
2137For ease of programming you can consider the maze as a 2D array with colors represented by below integer and characters (in capital letters). • B - Black • W -White • G- Green • R- Red R B W B W W W W W W B W B B W W W W W W W B W B W W W B W W W W B B W W W B W W W B W W B B B B W B W B W W B W W W B W W W B B B W W B W W W B W W B W B W W W B W B W W W W B B W W W W B W W W W W G Shortest Route Problem: • Solution that finds the shortest Route between Red and Green White will have 1 Weight. Red and Green carry no weights. Shortest path is the path with less weight when you add up the weights in the path.

IBM,
4 6808In my project iam integrating telephone line using some
bridge. To connect my project to that telephone line they
have give some jar file. Using dat i connected with that..
To handle that event like call attented, call disposed and
idle time they have give one event listener class.. I did
every thing and this class is alsoo called when a
particular event is fired. The only thing is i wanna call
EJB from that event listener method.. But the EJB is not
getting initated and exception is thrown. This below shownn
error is occured only i try to call it from this event
listener class. In other places EJB calling is working
fine..
