How do I pass an array as an argument to a Constructor?

[Colby Allen]

Ok here is my situation. I have this array in my demo program ---> double[] badScores = {97.5, 66.7, 88.0, 101.0, 99.0 }; I need to pass this as an argument to my parametrized constructor. I know how to do it going down the line with user input. But this for some reason is throwing me for a loop since I am just given an array instead of having a user input the numbers.

Edit: *facepalm* Ok it never fails right after I post an issue I figure it out just like that.

Anyway for anyone searching for this issue here is how I did it.

TestScores(double[] s)
	{
		for( int i = 0; i < SIZE; i++ )
		{
			scoreArray[i] = s[i];
		}
	}

Just a hint: you can use System.arraycopy to do the copying for you. So instead of

for( int i = 0; i < SIZE; i++ )
{
    scoreArray[i] = s[i];
}

you can simply write

System.arraycopy(s, 0, scoreArray, 0, SIZE);

This means: copy SIZE elements from s to scoreArray, starting at 0 for both s and scoreArray.

No problem. I hate a wasted post, so if somebody searches for this post then I want them to be able to find what they are looking for. Also this forum has helped me plenty, so I like to give back when I can.

Thanks for the tip! I will try to remember that in the future.
