Answer 4

if you do something like:
var p = new FlowersColors() .a2(0);
System.out.println(p.color );

you can get error: cannot find symbol: variable color
because a2() returns String and then p is String and it has not color

//try this
public static void main(String[] args){
var p = new FlowersColors();
p.a2(0);
System.out.println(p.color );
System.out.println(p.numberOfcolor );
}
