Value assignment and Comparison

Assignment operation: + =-= * =/=

Int G = 3; G + = 4; // equivalent to G = G + 4system. Out. println (g); // The result G is 7

Note:

Short S = 3; // s = S + 4; If compilation fails, the accuracy may be lost because he performs two addition operations and value assignment operations, 4. For int type, the short cannot be used to install S + = 4; // The compilation is successful, because it only performs one value assignment operation and there is an internal automatic conversion mechanism.

 

Comparison operator:

NOTE 1: The comparison operator results in the boolean type, that is, either true or false.
Note 2: The comparison operator "=" cannot be mistakenly written as "= ".

Int R, T, Y; r = 3; t = 4; y = 5; system. Out. println (r = y); system. Out. println (T! = Y );//! = Not equal
