instead of using try{}catch{} blocks throw an
ApplicationException and make suclass to that class and
extend RuntimeExceptions to ApplicationException class

public void read(String name)throws ApplicationException{
badurl(name);
numberFormate(name);
}
public void badUrl(String name)throws BadUrlException{
}
public void numberFormate(String name) throws
BadNumberException{
}
ApplicationException extends RuntimeException{
}
BadUrlException extends ApplicationException{}
BadNumberException extends ApplicationException{}

First best way is use built-in exception classes wherever possible, you don't need to create your custom exception class to represent every scenario, so try to use existing exception classes

Second best way of handling exception is creating custom exception for specific scenario by extending our class with Exception class.

Consider the following example...

public class BookSearchException extends Exception {
public BookSearchException(String message) {
super(message);
}
}
