Can you catch more than one exceptions in a single catch block?

Yes. If the exception class specified in the catch clause has subclasses, any exception object that is a subclass of the specified Exception class will be caught by that single catch block.
E.g..

try {
// Some code here that can throw an IOException
}
catch (IOException e) {

e.printStackTrace();

}

The catch block above will catch IOException and all its subclasses e.g. FileNotFoundException etc.
