The animation speed is medium speed (or normal speed) when the (general) value is 1.0, the slow speed is 0.33 of the normal speed, fast to 1.7 of the normal speed. The higher the value, the faster the range is 0-10000.Screen resolution: The number of pixels per centimeter and the definition of the "1 cm" length on the screen.

sentence compilation does not pass Final New StringBuffer ("111"); a.append ("222"); // compiled byAs you can see, final is valid only for the reference "value" (that is, the memory address), which forces the reference to point only to the object that was initially pointed to, and changes its point to cause a compile-time error. Final is not responsible for the change in the object it points to.Summarize　　A reference to the local variable data and objects (String, array, object, and so on) that
