..• 5. Consider an arrow starting at the origin and ending at the point (x, y). Turning the arrow by 90 degrees changes the coordinates as follows: Xafter = Ybefore Yafter = -Xbefore (*pefore» Y'before) 002 'after> Yafrer) Complete this program that computes and prints two turns of a given arrow. Develop the equations that replace the variables x and y with their rotated values. Copy them and paste them for another turn. codecheck-bjlo-1e-02_02 Turn.java
