How to modify all array elements in 1 line?

float[] point; point = {2, 3};
How does one do this?
Do you really have to define elements individually?

float[] point = {2, 3};

You can do that. If you want to change them all later, you will have to loop and change the values:

for(int i=0;i<point.length;i++) point[i] = i;

Or, since it looks like you're using an array to do a point, consider using a PVector:

PVector p = new PVector(2,3);
p.x = 0;
p.y = 1;

I would avoid using "point" as the name of a variable; it can be confusing.

But how do you do stuff that a loop cannot do?
float[] notPoint; notPoint = {0.2, 1.5, -500, 67, 3.1415};

GoToLoop

Java only allows array instantiations w/ just curly braces when we're also declaring the variable to hold its reference at the same time;

float[] notPoint = { .2, 1.5, -500, 67, PI };

Otherwise, we're gonna need to specify the type before the curly braces as well:

float[] notPoint;
notPoint = new float[] { .2, 1.5, -500, 67, PI };
