URI.create() vs new URI()

Question

A uri could be created in two ways:

URI uri = new URI("https://www.google.com/");

Or,

URI uri = URI.create("https://www.google.com/");

I was wondering which is a better practice. I haven't noticed any performance differences and I've read the documentation, however it was a bit difficult to understand. Any insight on this is appreciated.

Answer 1

Reading the docs, it differs in the usage.

Creates a URI by parsing the given string.This convenience factory method works as if by invoking the {@link URI(String)} constructor; any {@link URISyntaxException} thrown by the constructor is caught and wrapped in a new {@link IllegalArgumentException} object, which is then thrown.

This method is provided for use in situations where it is known that the given string is a legal URI, for example for URI constants declared within in a program, and so it would be considered a programming error for the string not to parse as such. The constructors, which throw {@link URISyntaxException} directly, should be used situations where a URI is being constructed from user input or from some other source that may be prone to errors.

@param str The string to be parsed into a URI

 * @return The new URI
 *
 * @throws  NullPointerException
 *          If {@code str} is {@code null}
 *
 * @throws  IllegalArgumentException
 *          If the given string violates RFC 2396

public static URI create(String str) {
    try {
        return new URI(str);
    } catch (URISyntaxException x) {
        throw new IllegalArgumentException(x.getMessage(), x);
    }
}
