Which of these lines when placed in line 1 will create an instance of class Inner? (select all that apply).


class Outer {
	public class Inner { }
	Inner getInner(){ return new Inner(); }
	public Outer() { }
}

public class Starter {
	public static void main(String[] args) {
		//1
	}
}

new Outer();
new Inner();
(new Outer()).new Inner();
Outer.getInner();
Outer o = new Outer(); o.new Inner();
new Outer.Inner();
new Outer().Inner();

Explanation

Neither class Inner, nor method getInner() are static, therefore you need to have an instance of class Outer to create an instance of class Inner.
