bitwise-OR-assignment operator|= is a bitwise-OR-assignment operator. It takes the current value of the LHS, bitwise-ors the RHS, and assigns the value back to the LHS (in a similar fashion to += does with addition).
What is && and || called?
&& and || are called short circuit operators. When they are used, for || - if the first operand evaluates to true , then the rest of the operands are not evaluated. For && - if the first operand evaluates to false , the rest of them don't get evaluated at all.
What does a question mark in Java mean?
In generic code, the question mark (?), called the wildcard, represents an unknown type. The wildcard can be used in a variety of situations: as the type of a parameter, field, or local variable; sometimes as a return type (though it is better programming practice to be more specific).
What is && and || in Java?
The && and || operators perform Conditional-AND and Conditional-OR operations on two boolean expressions. These operators exhibit "short-circuiting" behavior, which means that the second operand is evaluated only if needed.
Why && is used in Java?
The symbol && denotes the AND operator. It evaluates two statements/conditions and returns true only when both statements/conditions are true.
What is the other name for a question mark colon (? :) operator in Java?

IS & & && the same?
"&&" and "and" both are logical AND operations and they do the same thing, but the operator precedence is different.
What is a key difference between && and &?
& is a bitwise operator and compares each operand bitwise. It is a binary AND Operator and copies a bit to the result if it exists in both operands. (A & B) will give 12 which is 0000 1100. Whereas && is a logical AND operator and operates on boolean operands.
What is difference between && and & in C?
&& (logical and operator) - The left and right operands are boolean expressions. If both the operands are non-zero, then the condition becomes true. & (bitwise and operator) - The left and right operands are integral types. Binary AND Operator copies a bit to the result if it exists in both operands.
What does double ampersand mean?
In programming, a double ampersand is used to represent the Boolean AND operator such as in the C statement, if (x >= 100 && x >= 199). In HTML, the ampersand is used to code foreign letters and special characters such as the copyright and trademark symbols. See ampersand codes and address operator.

Conclusion
- In java, ++ and — signs represent increment and decrement operators, respectively. The ++ and — operators respectively increase and decrease the variable’s value by 1. Both these operators can be used as either prefix or postfix. In prefix, the increment/decrement operator comes before the variable, while in the case of postfix, the increment/decre...
