I haven't used the math class for a long time. I cannot remember it clearly, so that I can make mistakes when I read a scjp question. I will refresh my memory today. Remember! Public class t {public static void main (string [] ARGs) {system. out. println (math. round (-4.1); system. out. println (math. round (-4.8); system. out. println ("---"); system. out. println (math. ceil (-4.8); system. out. println (math. floor (-4.8 ));}} This sectionCodeOutput: -4-5----4.0-5.0 About Ceil and floor:

Antennas are rectangular, circular, and rod-shaped. Generally, the longer the communication distance is, the larger the size of the antenna. However, in actual use, when tags are attached to an item, even the RFID tags of the business card size are too large. In fact, the size and shape of the RFID tag in use need to be selected based on the communication distance. Currently, antenna materials include aluminum, copper, and so on. The price of alumi

See http://www.bkjia.com/kf/201110/107462.html In Android, the display effect of default controls is often not very beautiful. We can create an XML file under drawable, which contains the shape label and its related attributes. For example, you can set a LinearLayout border, fill color, and rounded corner effect in this way. For example, in the following code (today_but_selector.xml ): Android: right = "10dp" android: bottom = "10dp"/> This xml file

1. background selector (IN res/drawable/, usage: android: background = "@ drawable/XXX ") 2. text color selector (IN res/color/, usage: android: textColor = "@ color/XXX ") Note: android: color is not displayed when res/drawable/XXX. xml is displayed. Similarly, android: drawable is not displayed when res/color/XXX. xml is displayed. 3. Background gradient (IN res/color/or res/drawable /) Res/drawable/selector1.xml: Android: startColor = "# A5D245"/> Android: startColor

8. Android implements a function similar to a Shape that only requires a certain border ., 8. androidshape For example, you can use layer-list to set the border color on the first layer. The second layer can be used to hide the section that does not belong to the border on the first layer. For example, the second layer hides the 1dp height color at the top and bottom of the first layer, and the effect is to implement the top and bottom borders.
