I want to fetch data from database to jsp Page. Whenever we type a word relating words starting with letter typed should be filled automatically by fetching from the DB like a drop down.
Define a new exception called “NotMemberException”. The exception must be thrown if the registration number entered by the user does not exist in the list of StudInfo. Your program should catch the exception as follows. It should first try to see if the number before and after the one entered exists. If so, it informs the user that they probably made a typo and provides them the name of the found student. If neither is found it must simply inform the user that such registration number does not exist.

Hello, I have an assignment due and I am having trouble starting it. Everytime I try to attempt it I get lost, and can't think of which classes to create other than the main do it all class. Could u help me break down my assignment a little please? The assignment asks for me to make a program that can simulate traffic in a network of roads that have sensors at each intersection and I am to record the car's registration number, and name of the sensor, and time it passed into a text file. I don't need help with the coding but just the setting it up and structuring part. Thanks
i am doing problem solving with robotics and was wondering how do you calibrate light sensor using java

Each player starts-out with a cumulative score of zero. Then each player rolls three
dices and a random number appears for each dice. The summation of each number is
added in each player’s score. The winner is the player that has the highest score in x
