Description Ayushman Jain

BETA_JAVA7

public class DiamondTest<T> {
	
	public <U> DiamondTest(T t) {
		
	}

	public static void main ( String[] args ) {
		DiamondTest<String> d = new <Integer> DiamondTest<>();

	}

}

On the error at <Integer> above, there can be a quick fix which inserts <String> in place of <>.

(Sorry if i'm filing a dup.)

The RHS also needs an actual method argument (e.g. ""). Then the best fix would be to turn it into
    new DiamondTest<>("");
not
    new <Integer>DiamondTest<String>("");

I don't think we should spend time on this, since explicit constructor type arguments are rare in practice. In the given example, the compiler would first have to be fixed to compute the right type binding for the ClassInstanceCreation.
