Bitwise AND short circuit and difference: Both bitwise AND logical operators, both sides can be Int or boolean expressions. When both sides are int, the number on both sides of the operator must be converted to the binary number before calculation. The short circuit and () must be a Boolean expression. Example: What is the value of 12 5? A: 12 is converted to 1100 (the first four digits are omitted)

The short type can represent the number of 32-bit machines: 2 ^ 16 = 65536. For unsigned short, the range is 0 to 65535. If it is signed, the range is-32768 to 32767. When it is 32767, the sign bit is 0, and the remaining 15 digits are 1. When it is-32767, the sign bit is 1, the remaining 15 digits are 1. Because there is a signed number, there is a positive 0 and a negative 0. Negative zeros are used to re

1. There are three methods to process key events in Android gridview: Public Boolean onkeydown (INT keycode, keyevent event) Public Boolean onkeyup (INT keycode, keyevent event) Public Boolean onkeylongpress (INT keycode, keyevent event) Obviously, long-press events are handled in the onkeylongpress function. If the time of the gridview is long, the corresponding short press event (gridview. setonitemclicklistener (), and the processing of Long-key ev

Short S = 1; S = S + 1; CompilationFailedShort S = 1; S + = 1; why can I compilePassSo? Another problem is that implicit type conversion can be automatically converted from small to large, that is, byte-> short-> int-> long. If the precision is lost in turn, it must be performed.Display type conversionS + = 1 means different from S = S + 1, S = S + 1: Execute S + 1 first and then assign the result to S. Be
