One of the most basic uses of computers is to perform mathematical operations, and as a computer language, Java also provides a rich set of operators to manipulate variables. We can divide the operators into the following groups:
Arithmetic
Introduction?? The self-increment operator + + is available in the JDK, and the decrement operator--。 Each of these two operators is used in two ways: prefix (+ a,--a), suffix (a++,a--). May say here, said not to have the reader will Spit Groove
String operator ******************1. The string operator is one. This is a point where the left string and the right string are stitched together into a string.2. For example $ A = "Sin"; $b = "Love Xiao Qian"; So $ A. $b is "Sinsing Yong Love Xiao

Speaking of operators, basically all kinds of programming languages are involved, the use of a similar way. Here is a simple collation of JavaScript here today.In general, operators are more than the comparison, can be divided into the following
overloaded operators and conversions--Self-increment/self-decrement operatorIntroduction:Self-increment, the decrement operator is often implemented by classes such as iterators that provide pointers-like behavior to access elements in a sequence.
+ 、-、 *,/, = Priority
1. Priority level As with mathematics, C language stipulates multiplication and subtraction before adding and reducing . In other words, the multiplication and division operators have a higher precedence
All summary points are for reference only and are not guaranteed to be completely correct1. The difference between a reference and a pointer① references must be initialized, pointers can not be initialized② reference cannot be null, pointer can be
