### Question:
Vector3D { public static float distanceDotLine(float[] dot, float[] lineA, float[] lineB) { float[] v_l = createVector(lineA, lineB); float[] w = createVector(lineA, dot); float[] mul = vectorMultiply(v_l, w); return vectorLength(mul)/vectorLength(v_l); }  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 distanceDotLine() throws Exception { }
