Yes, it is a shorthand form of. count = getHereCount(index); count = getAwayCount(index); It's called the conditional operator. Many people (erroneously) call it the ternary operator, because it's the only ternary (three-argument) operator in Java, C, C++, and probably many other languages.
Jan 2, 2010 · It is the Bitwise xor operator in java which results 1 for different value of bit (ie 1 ^ 0 = 1) and 0 for same value of bit (ie 0 ^ 0 = 0) when a number is written in binary form. ex :-. To use your example: The binary representation of 5 is 0101. The binary representation of 4 is 0100.
++a is prefix increment operator: the result is calculated and stored first, then the variable is used. a++ is postfix increment operator: the variable is used first, then the result is calculated and stored. Once you remember the rules, EZ for ya to calculate everything!
May 15, 2017 · n%10 means the modulus of 10, that is the remainder you get when you divide with 10. Here it is used to get each digit. Example: Say your number is n = 752. n%10 = 2, n/10 = 75. So you add 2 to the sumDigits(75) Now, n%10 = 75%10 = 5. This is the digit to be added and so on, till your n >= 10. When it is < 10, you have a single digit that you ...
May 26, 2013 · @TylerDurden Without >>> (e.g. when you use >>) the most significant bit (AKA "the sign bit") of a 32-bit or a 64-bit value gets special treatment - it gets replicated in the new sign bit after the shift, so the sign of the value after the >> shift remains the same.
Apr 9, 2011 · While && operator will stop evaluating the second argument if the first argument's result is false. One more difference between these two is, Bitwise & operator is applicable for boolean as well as integral types. While short-circuit && operator is applicable only for the boolean type. We can write.
The diamond operator provides no type information, it just says the compiler, "it'll be fine". So by omitting it you can do no harm. At any place where the diamond operator is legal it could be "inferred" by the compiler. IMHO, having a clear and simple way to mark a source as Java 7 would be more useful than inventing such strange things.
The arrow operator is used to create lambda expressions, linking/separating parameters with the lambda body. syntax: (parameters) -> {expression}; It is also an efficient way of implementing functional interfaces like onClickListeners in java. answered Dec 2, 2022 at 10:09.
All the answers here are great but, just to illustrate where this comes from, for questions like this it's good to go to the source: the Java Language Specification. Section 15:23, Conditional-And operator (&&), says: The && operator is like & (§15.22.2), but evaluates its right-hand operand only if the value of its left-hand operand is true.
The || operator can only be used, in Java, where a boolean (true or false) expression is expected, such as in an if statement like the above. So pretty much in an if or a conditional operator (that ?...: thing, sometimes called the ternary operator).
