Defines a pointclass used to represent points in three-dimensional space (with three coordinates). Requirements are as follows:

(1) You can generate a point object with a specific coordinate.

(2) provides a way to set three coordinates.

(3) provides a way to calculate the square of the distance from the origin of the point.

(4) write the main class program validation.

 Public classPoint {Private intA,b,c; Point (intAintBintc) { This. a=A;  This. b=b;  This. c=C; }     Public intGeta () {returnA; }     Public voidSetA (inta) { This. A =A; }     Public intGetb () {returnb; }     Public voidSETB (intb) { This. B =b; }     Public intGetC () {returnC; }     Public voidSETC (intc) { This. C =C; }     Public voidJuli () {System.out.println ("Coordinates" +a+ "," +b+ "," +c+ "the distance from the origin of the square =" + (a*a+b*b+c*c)); }     Public Static voidMain (string[] args) {point P=NewPoint (2,2,2);        P.juli (); P.seta (3); P.SETB (5); P.SETC (9);    P.juli (); }
