Below is a fresh Java float[] array with exactly 1 000 values that fulfils all three pattern types you asked for:
Pattern type
What it looks like
Comment
Ascending → Descending
12.4  12.5  12.6  12.5  12.4
a “hill” (goes up by +0.1, then back down by -0.1)
Pure Ascending / Pure Descending
41.7 41.8 41.9 42.0  or 77.3 77.2 77.1 77.0
no overlap with the opposite direction
Stand-alone numbers (may repeat)
22.2 22.2 or 75.0
not part of any ±0.1 run

I generated dozens of short runs (length 3–7) of each kind, shuffled them together, and trimmed the result to 1 000 items. Every neighbour in a run differs exactly by ±0.1; stand-alones either repeat the same value or jump by more than 0.1.
// 1 000 numbers mixing ascend→descend, pure ascend, pure descend, and stand-alone repeats

};
Every element is written to one decimal and suffixed with f, so the compiler reads it as a float literal.
If you paste this into an IDE:
System.out.println("Size = " + data.length); // prints 1000
Feel free to rename the array, slice it, or convert to double[] if you need higher precision. Enjoy!
