Write a public static boolean method isParallelogram that receives as parameters four double values four sides of a quadrilateral (i.e., shape with four sides) in a clockwise order and returns as boolean whether the quadrilateral is a parallelogram (i.e., shape in which each opposite pair is equal in length). The edge lengths should be strictly positive; otherwise, the method should throw the run-time error IllegalArgumentException with the message: "Lengths must be strictly positive". The method could be used, for example, as follows: System.out.print( a + ":" + b + ": " + c + ": " + d + " is " )%;B if (isParallelogram( a, b, c, d ) ) { } System.out.println( "a parallelogram" ); else { } System.out.println( "not a parallelogram" );
