Can I remove generic type parameters from object constructors in Java?

In Java, you must write:

Pair<String,String> pair = new Pair<String,String>("one","two");

It would be nice to infer these types for you, so you can at least do this:

Pair<String,String> pair = new Pair("one","two");

And skip the general parameters again

You can create a static method that can cheat like this:

public static <T,S> Pair<T,S> new_(T one,S two) {
    return new Pair<T,S>(one,two);
}

Then use it: pair new _ (“one”,“two”).

Can type inference be built in constructors so that hacking can be avoided?

What I think is:

public <S,T> Pair(S one,T two) {
    this.one = one;
    this.two = two;
}

But you will encounter generic conflicts Does anyone have an idea?

Solution

There is usually a help method that will hint at your type

Pair<String,String> pair = Pair.of("one","two");

Then it doesn't seem to be such a hacker

It would also be nice if Java had a built - in pair class
