### Question:
Vector3D { public static float vectorLength(float[] vector) { return (float) Math.sqrt(vector[x]*vector[x] + vector[y]*vector[y] + vector[z]*vector[z]); }  static float[] vectorMultiply(float[] lhs, float[] rhs); static float scalarMultiply(float[] lhs, float[] rhs); static float distanceVertices(float[] left, float[] right); static float vectorLength(float[] vector); static float[] createVector(float[] start, float[] end); static float distanceDotLine(float[] dot, float[] lineA, float[] lineB); static float distancevertexSegment(float[] dot, float[] segmentStart, float[] segmentEnd); static final float Epsilon; }### Answer:
@Test public void vectorLength() throws Exception { }
