variable on the left and the value on the
right and assigns the result to the variable
on the left.
FOR ONLINE READING ONLY
Performs a left bitwise shift on the variable a <<= 2; // a = a << 2
on the left by the number of positions
specified on the right and assigns the
result to the variable on the left.
>>= Performs a right bitwise shift on the a >>= 1; // a = a >> 1
variable on the left by the number of
positions specified on the right and assigns
the result to the variable on the left.
>>>= Performs an unsigned right bitwise shift a >>>= 1; // a = a >>> 1
on the variable on the left by the number
of positions specified on the right and
assigns the result to the variable on the
left.

(f) Ternary operator
The ternary operator in Java is a shorthand for an if-else statement. It is used to
evaluate a boolean expression and return one of two values based on the result of
the evaluation.

Syntax
In Java, the ternary operator (also known as the conditional operator) has the
following syntax:

variable = (condition) ? expression1 : expression2;

In this syntax;

condition: Represent a boolean expression that evaluates to either true or false.

expression 1: Represents “If the condition is true, the variable is assigned the value
of expression1”.

expression 2: Represent “If the condition is false, the variable is assigned the value
of expression2”.

The Program Example 5.10 demonstrates the ternary operators:
