Java 0 Basic Series 004--operators

The most basic operators are familiar with the + 、-、 *,/, which are binocular operators
Logical operators && (logic and), | | (logical OR),! (logical) is an operator that operations on a Boolean type, where &&, | | | It's the eyes, it's monocular.
A&&b as long as a, b any one variable is false, the result of the operation is false, no is true
a| | As long as any one of the B is true, the budget result is true.
!a, when a is true the result of the operation is false and the result of the operation is true when a is false

Bitwise operator ~ (take No), & (Bitwise AND), | (bitwise OR), ^ (XOR) is a bitwise operator
such as the a=001,~a operation will become 110;&, |, ^ are binocular operators
Any one of the & operators is 0, the result is 0, otherwise 1, such as a=1001,b=1000, the result of A&b is 1000
Any one under the | operator is 1, the result is 1, otherwise 0, such as a=1001,b=1000, the result of A&b is 1001
Under the ^ operator, the two bit values are the same, the result is 1, otherwise 0, such as a=1001,b=1000, the result of A&b is 1110

>> (Shift right) \<< (left), shift left is equal to multiply by 2, left 1 is multiplied by one 2. Shift right is equivalent to dividing by 2, moving one right by one and dividing by a 2.

Extension operators
A + = B equates to A=a+b
A-= B is equivalent to A=a-b
A *= B is equivalent to A=a*b
A/= B is equivalent to a=a/b

String connector +, two strings with a + symbol, the role of + becomes the connection of two strings

Trinocular operator
The logic of writing? A:B, when logic is true, the result of the operation is a. When logic is false, the result of the operation is B

//operator Public classOperator { Public Static voidMain (string[] args) {intA = 1,b = 2; System.out.println ("a+b=" +a+b);//addition Operation                Booleanc =false, d =true; System.out.println ("C&&d=" + (c&&d));//Logic and Operations//Decimal for Binary 1000 decimal is 8,1001 9        intE = 8&9; System.out.println ("1000&1001=" +integer.tobinarystring (e));//bitwise operator, tobinarystring turns the result into binary so we could see                    intf = 2<<3;//displacement Operation 2<<3 equivalent to 2*2^3System.out.println ("2<<3=" +f); intg = 1<2?5:6;//Three mesh operator, the result of 1<2 logic is true, so the result of the operation is 5System.out.println ("1<2?5:6=" +g); }}
