 Vector API (introduced in Java 16)

The Vector API provides a set of classes and methods for efficient vectorized computations on arrays of numeric data. It enables better utilization of SIMD (Single Instruction, Multiple Data) instructions for improved performance. Here's a simple example:

import java.util.Arrays;

import java.util.stream.*;

float[] array1 = new float[]{1.0f, 2.0f, 3.0f};

float[] array2 = new float[]{4.0f, 5.0f, 6.0f};

VectorFloat vector1 = VectorFloat.fromArray(array1, 0);

VectorFloat vector2 = VectorFloat.fromArray(array2, 0);

VectorFloat sum = vector1.add(vector2);

float[] result = sum.intoArray();

System.out.println(Arrays.toString(result)); // [5.0, 7.0, 9.0]
