May 11, 2010 · The unsigned right shift operator >>> shifts a zero into the leftmost position, while the leftmost position after >> depends on sign extension. In simple words >>> always shifts a zero into the leftmost position whereas >> shifts based on sign of the number i.e. 1 for negative number and 0 for positive number.
Jul 16, 2021 · 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 ...
Aug 5, 2015 · 110. The @ symbol denotes a Java Annotation. What a Java annotation does, is that it adds a special attribute to the variable, method, class, interface, or other language elements. (This can be configured when you declare the annotation) When you add an annotation to something, other parts of the program can check whether something has an ...
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. This is different for unsigned types in languages that have them (say, C/C++ or ...
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.
Theoretically you can use dollar sign in variable names, but it's strongly discouraged because that symbol is used internally by the compiler(e.g. inner or anonymous classes's name). Please refer to two related questions on the stackoverflow: What is the meaning of $ in a variable name? and Java class name containing dollar sign fails to compile if an inner class is present
Jan 13, 2014 · The integral types are byte, short, int, and long, whose values are 8-bit, 16-bit, 32-bit and 64-bit signed two's-complement integers, respectively, and char, whose values are 16-bit unsigned integers representing UTF-16 code units. – Marko Topolnik. Jan 13, 2014 at 11:07. 1. @zapl yes, the same as byte and short, but fundamentally it is a 16 ...
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).
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.
Aug 19, 2017 · It's being used there to keep a value in range: If name.length is less than 4, 7, or 50, the result of % name.length on those values is a value that's in the range 0 to name.length - 1. So that code picks entries from the array reliably, even when the numbers (4, 7, or 50) are out of range. 4 % 4 is 0, 7 % 4 is 3, 50 % 4 is 2.
