Bitwise logical operators & (AND) | (OR) ^ (XOR) operate on the two numbers expressed in 32 bit integer form and perform indicated logical operation on each bit separately
|
|
<< is bitwise left shift discarding bits at left (high order) and zero filling at right
|
|
>> is bitwise right shift propagating the sign bit in high order (oposition 31)
|
|
>>> is zero fill right shift with no special treatment of sign bit
|
|
Boolean operations are && (AND), || (OR), ! (NOT) and can only operate on boolean variables which are true or false
|
|
Comparison Operators are == > >= < <= != which can be used on numerical OR string variables
|
Concatenation operator + joins two strings together
