How can I access methods of different classes in java using the array of type Object -
here code: public static void main(string args[]) { circle objcircle = new circle(5); square objsquare = new square(5); triangle objtriangle = new triangle(3, 4); sphere objsphere = new sphere(5); cube objcube = new cube(5); tetrahedron objtetra = new tetrahedron(5); object[] shape = new object[5]; shape[0] = objcircle; shape[1] = objsquare; shape[2] = objtriangle; shape[3] = objsphere; shape[4] = objcube; shape[5] = objtetra; for(int = 0; i<shape.length; i++) { //problem occured in section of code system.out.println(shape[i].getarea()); } } } i have 6 different classes , of them have getarray() method definition of own. want print values getarray() method returns different classes using shape array. define interface below. implement interface in class circle , square .. public interface shape { public double getarea(); } then can different classes getarea below. shape [] sha
