Algorithm (4th edition) -1.2.2 abstract data Type example

Summary: As the name implies.

Focus:

1. Geometric objects: A Natural example of object-oriented programming is designing data types for geometric objects.

Point2d.java is a data type for points in the plane.

Interval1d.java is a data type for one-dimensional intervals.

Interval2d.java is a data type for two-dimensional intervals.

Interested to study!

2. The Java language provides special support for string initialization and connection: We can create and initialize a string directly using a string literal instead of a constructor, and you can use the + operator instead of the concat () method.

// You do not need to use string a = new String ("The Time");
