Constructors Within Methods
I'm trying to call a constructor in a method (the method performs an action on the object and returns a new object of that type with the changes made to it). I've already tried but my IDE underlines the second part of my constructor call (ie. for the constructor call `Object obj = new Object(int n);` `new Object(int n)` is underlined. Is this possible at all or am I just calling the constructor wrongly?

Update: I just did a Google search on this question and apparently it's impossible. I'll just have to find another way to get what I want done.
Thanks for everyone's help (#more Google searches).

Can I see code or that part of code..?
Can't say with this info..
Edit:
When calling a method just pass value..
No need to put type...

You dont need to mention the data type while calling constructor.Declare 'int n' before calling constructor
Write the underlined line as this:
Object obj=new Object(n);

It looks like my code is horribly wrong. I'm going to rewrite it from the ground up. I'll come back here if I need any help.
Thanks!

Here's part of current code (I can't share the entire code 'cause it's an assignment). What I really want to do is create a second instance of the object so that my method here only affects the second instance and returns it.
//Think of the object as a square grid. This method is supposed create a new
//object and flip it's outer elements, returning the new grid.
void upsideDownFlip() {
this.size = n;
Squarelotron atarashi = new Squarelotron(n);
squarelotron [0] = squarelotron [5];
squarelotron [5] = Squarelotron.squarelotron [0];
squarelotron [1][0] = squarelotron [1][5];
squarelotron [2][0] = squarelotron [2][5];
squarelotron [3][0] = squarelotron [3][5];
squarelotron [4][0] = squarelotron [4][5];
for(int i = 0; i < squarelotron.length; i++) {
System.out.println(Arrays.toString(squarelotron[i]));
}
return;
}
Please ask for any necessary further information.
