Basic operators, remainder, logical operators, logical operators, bitwise operators, shift operators in Java

Precautions:

1. Constants are assigned at compile time, and variables are allocated in memory when they are run.
2. Assignment operator + =-+ *+%= \= The Java compiler enforces type conversions

Residual:

In Java, it is time to take the remainder operation, and the sign of the result is determined by the divisor.

Bitwise operators: direct manipulation of bits.

& (with)6 & 3 = 2      0000 0110         can treat 1 as true  &  0000 0011        0 as false-- ----------------     0000 0010        2|  (OR)      Consistent with on ^ (XOR)    and on the same  rule: if the operand A is consecutive or the same operand two times, then the result is the operand a~ (take the inverse)    binary take the inverse  = 8

Shift operators:

<<  (left shift)        rule: A number of operands to the left is multiplied by 2 n >>  (right)        an operand is moved to the right, if the operand is a positive number , then the left vacant bit uses 0 complement, and vice versa. >>> (unsigned Right shift) is   uniformly used 0 to complement either positive or negative.

Ternary operator: Boolean expression-value 1: value 2;
