then (a and B) or c. under normal circumstances, if a is true, a and B will return B. If B is a string or value, it is 'true'. Therefore, B or c will return B directly, design that meets the expectation of "a is true, returns B.
However, if B is a variable and the variable is null (for example, not defined), B is false, and B or c returns c. in this case, "a is true, but c is returned.
Therefore, in order for expression a and B or c to work normally, B must be true. if B is not true, only if-el

For example, the renminbi in your life, 5 yuan banknotes, will not become 50 or 500 yuan in any of the scenes you use.
Programming is code and computer warfare, the data type is the code of the various classes, as long as the code camp, must belong to a certain class. Constants include integer constants, floating-point constants, character constants, and, as long as the cla

Some time ago, in my blog on cnblogs, I talked about:
References/pointers in java are not similar to references/pointers in c ++/C.
Java reference, equivalent to c ++ pointer (fun3 ). Java references can be assigned null values, while c ++ references (see fun2) cannot be assigned null values. c ++ pointers can be assigned null values (fun3 ).In Java, there is no syntax for c ++ reference (fun2.
The results raised unnecessary questions. I write a blog to compare and reference the pointers and re
