201671010116.2016-2017-13 "Java Programming" 13th Week study Summary

This week, through the theory class test and the experimental course program to consolidate the 1-5 chapters of knowledge points. Because the understanding of the program is a bit confusing, so the last big question in the test is not finished. Compared with the last Test, the biggest point is the program reading problems and programming problems. The reasons are as follows:

1. Understanding the procedure is not thorough, can not link up and down the program

2. Do not see the program code, the wrong program object statements as output statements

3. The mastery of knowledge points is not strong.

Through two Tests let me from the wrong problem to find their own missing items, through the data to grasp the usual less attention and not commonly used knowledge points.

The new knowledge point of this week is the 11th Chapter-----event handling. Some of these common events are mouse movement, mouse click buttons, mouse click button buttons, text box background settings, menu items in the menu, and so on.

Actions that can trigger an action event, mainly include:

(1) Click the button

(2) Double-click an option in a list

(3) Select menu item;

(4) Enter the carriage return in the text box.

The type of mouse event is mouseevent, when a mouse event occurs: The MouseEvent class automatically creates an event object, as well as the x and Y coordinates of where the event occurred, as an event return value.
