$1.$ Submit $.$java file: $($The Point class$)$ Design a class named Point that meets the following requirements: $.$ Two data fields x and y for representing a point with getter methods $.$ A no$-$arg constructor that constructs a point for $(0,0).$ A constructor that constructs a point with the specified x and y values $.$ Override the equals method. Point pl is said to be equal to point p$2$ if pl$.$x$=$p$2.$x and pl$.$y$=-$p$2.$y$..$ Override the hashCode method. $($For reference, see the implementation of the Point$2$D class in the Java API.$)$
