Problem statement

Implement a class Point that has three properties and a method. All these attributes (properties and methods) should be public. This problem can be broken down into two tasks:

Task 1

Implement a constructor to initialize the values of three properties: x, y, and z.

Task 2

Implement a method, sqSum(), in the Point class which squares x, y, and z and returns their sum.

Sample properties

1, 3, 5

Sample method output

35
