Reference no: EM13896093
JAVA) write a program IN JAVA that uses a method called quadrant that accepts as parameters a pair of double values representing an (x, y) point and returns the quadrant number for that point. Recall that quadrants are numbered as integers from 1 to 4 with the upper-right quadrant numbered 1 and the subsequent quadrants numbered in a counterclockwise fashion: xid-111609318_1 Notice that the quadrant is determined by whether the x and y coordinates are positive or negative numbers. Return 0 if the point lies on origin (point 0,0). return a -1 if the point is on the x axis, return -2 if the point is on the y axis. For example, the call of quadrant(-2.3, 3.5) should return 2 and the call of quadrant(4.5, -4.5) should return 4. The values for x and y should be entered by the user, and the where the point is located should be output by another method Name the class project3............................ based offf
