create a new program containing: A class named Point, with two fields: x and y and a constructor to set the values (see https://docs.oracle.com/javase/tutorial/displayCode.html?code=https://docs.oracle.com/javase/tutorial/java/javaOO/examples/Point.java) Add a new field that will keep a name for the point. It is empty string by default. Create a new constructor that will set the name to a predefined value. Add a print method that will print the coordinates in the format: NAME(X,Y).  A class name Rectangle, with a point of origin, height and width, four constructors and two methods (see https://docs.oracle.com/javase/tutorial/displayCode.html?code=https://docs.oracle.com/javase/tutorial/java/javaOO/examples/Rectangle.java) Add a new field that will keep a name for the rectangle. Create a constructor that will set the name, origin point and dimensions. Add a print method that will print the coordinates in the format: NAME(x, y, w, h)

• Using Objects https://docs.oracle.com/javase/tutorial/java/javaOO/usingobject.html  Instructions:

• Continue the above code(program):

  Also:

• create a new program containing:
  • A class named Point, with two fields: x and y and a constructor to set the values (see https://docs.oracle.com/javase/tutorial/displayCode.html?code=https://docs.oracle.com/javase/tutorial/java/javaOO/examples/Point.java)
    • Add a new field that will keep a name for the point. It is empty string by default. Create a new constructor that will set the name to a predefined value.
    • Add a print method that will print the coordinates in the format: NAME(X,Y). 
  • A class name Rectangle, with a point of origin, height and width, four constructors and two methods (see https://docs.oracle.com/javase/tutorial/displayCode.html?code=https://docs.oracle.com/javase/tutorial/java/javaOO/examples/Rectangle.java)
    • Add a new field that will keep a name for the rectangle.
    • Create a constructor that will set the name, origin point and dimensions.
    • Add a print method that will print the coordinates in the format: NAME(x, y, w, h)
• Imagine a robot head (square) with a rectangle mouth and nose and point eyes. Create the image in a new main program (class), giving suggestive names for points and rectangles. 
• Print the information for all the figures.
• Check which eye has the biggest x coordinate and print the result.
