No matter what language you use, you end up with business logic. In object-oriented programming languages, business logic is implemented in methods. Therefore, it is necessary for beginners to understand the basics of completing the Java class

All integer variables default to signed integers, JavaScript bitwise operation, is the use of 32-bit signed integer, which means that the result of its conversion is also a 32-bit signed integral typeIn JavaScript, all integer numeric variables are

We know that any information is stored in binary form in the computer. Bitwise operators are operators that operate on data in binary order. The bit operators in the C # language are: & and | Or ^ XOR or ~ Take the Fill >> Move Right Where
