More about Objects and Classes

The relational operations on primitive data are ==, >=, <=, >, <, and !=. They compare two data values, when those values' type has an ordering. For example, integers are ordered by size or magnitude. The result of a relational operation is a boolean value: either True or False. The relational operators on objects like Strings are different, and they are expressed as methods. Pay special attention to the equality method, equals().

    Assume that each row is independent of the others.

    code sectionpointA == pointBpointA.equals( pointB )pointB == pointCpointB.equals( pointC )
    Point pointA = new Point( 0, 0 );
Point pointB = new Point( 0, 0 );
Point pointC = new Point( 0, 0 );

    Point pointA = new Point( 13, -15 );
Point pointB = pointA;
Point pointC = pointA;

    Point pointA = new Point( 13, -15 );
Point pointB = pointA;
Point pointC = pointB;

    Point pointA = new Point( 13, -15 );
Point pointB = pointA;
Point pointC = new Point( 13, -15 );

    Point pointA = new Point( 13, -15 );
Point pointB = pointA;
Point pointC = pointB;
pointA.move( 8, 12 );

    Point pointA = new Point( 13, -15 );
Point pointB = pointA;
Point pointC = new Point( 13, -15 );
pointA.move( 8, 12 );


    

    

    

    



    Question 24:
    Do you imagine that professional programmers ever get == and equals confused?
