A Topic Introduction

Design a calendar Notepad for the GUI interface. The system combines the calendar and Notepad functions to make it easy for users to record content on any date or view a date.

1. The left side of the system interface is the calendar. The calendar can be flipped by year, and the current calendar year is reduced by one when the mouse clicks the previous year button, and when the left mouse button is clicked, the current calendar years plus one.

2. The calendar can also be flipped in a year or so, and when the mouse clicks the "Last month" button, the month of the current calendar is reduced by one, and the current calendar month is added one when the left mouse button is clicked.

3. Using the left mouse button to click on the selected date, such as the existing record content, the system will pop up a dialog box to indicate that the day has recorded content, and ask the user whether to display the content in Notepad.

4. Users can conveniently record content or view a date on any date.

Page the year by pressing the button "year Last" and "next year". Page through the month by pressing the button "last month" and "next month". Users can view their logs by entering the year.

Three The design of the module test cases, test results

There are 4 Java source files in this calendar of notebooks.

Calendarpad.java

The class generated by the Java file is responsible for creating the main window of this calendar Notepad program. The class contains the main method from which the program begins execution.

Year.java

This file is responsible for creating an object that manages the year.

Month.java

This file is responsible for creating the class object that manages the month.

Notepad.java

The file is responsible for creating Notepad.

Four Problems and solutions, experience

After a few days of effort, basically completed my Java curriculum design, but also basically achieved my needs in the analysis of the expected function. Through this course design, I learned from the textbook of the theoretical knowledge to practice, so as to further consolidate and enrich the knowledge I have learned, but also let me a deeper understanding of Java and its powerful features. At the same time to do this course design has further strengthened my ability to do. In order to complete this course design, did more preparation, internet access to a lot of relevant information, but also read a lot of related books. In these processes also intangible exercise My thinking analysis, encounter problems and find ways to solve problems through a variety of my ability.

From theory to practice, in the whole days of the day, can be said to be more bitter than sweet, but can learn a lot of things, at the same time can not only consolidate the knowledge learned in the past, but also learned a lot of books have not learned knowledge. Through this course design so that I understand the combination of theory and practice is very important, only the theoretical knowledge is far from enough, only the theoretical knowledge and practice of combining, from the theory to draw conclusions, can really serve the community, thereby improving their practical ability and independent thinking ability. In the process of design encountered problems, can be said to be difficult, after all, this is the first time, will inevitably encounter a variety of problems, at the same time in the process of the design found their shortcomings, the knowledge of the previous learning is not deep enough to understand, the mastery is not strong enough, so we must study theoretical knowledge, For the future practice to lay a good foundation.

Through this course design, I gain not only the practical application of the knowledge in the textbook, but also the basic habit of programming and development system is the process that should be paid attention to.
