Java has no logical XOR operator, according to sun. I would like to define one. Method Definition: As a method it is simply defined as follows: public static boolean logicalXOR(boolean x, boolean y) { return ( ( x || y ) && ! ( x && y ) ); } Method Call: This method is called in the following way: boolean myVal = logicalXOR(x, y); Operator Usage:

2014年10月15日 · The logical XOR operator does exist in Java and is spelled ^. To get the terminology right, in Java: &, | and ^ are called bitwise or logical operators, depending on the types of their arguments; && and || are called conditional operators. For details, see JLS § 15.22. Bitwise and Logical Operators onwards. There is no direct equivalent for ...

2010年1月2日 · That is because you are using the xor operator. In java, or just about any other language, ^ is bitwise xor, so of course, 10 ^ 1 = 11. more info about bitwise operators. It's interesting how Java and C# don't have a power operator.

2014年4月17日 · XOR is a bitwise operator, and its plain English description is "one or the other, but not both". Considering your truth tables, you need to look at them in a bit-wise fashion: x y x^y 0 0 0 <-same values, so xor is 0 1 0 1 <-values differ, so xor is 1 0 1 1 <-values differ, so xor is 1 1 1 0 <-same values, so xor is 0

2013年1月11日 · There is XOR function in Java - a^b For example: 5^3 = 6 Can you tell me the inverse function? If I have 6 and 3 can I get range of numbers which include number 5?

A Java char corresponds to a UTF-16 code unit, and in some cases two consecutive chars (a so-called surrogate pair) are needed for one real Unicode character (codepoint). XORing two valid UTF-16 sequences (i.e. Java Strings char by char , or byte by byte after encoding to UTF-16) does not necessarily give you another valid UTF-16 string - you ...

2022年2月7日 · I have a problem to writhe a function that finds the unique value from an array, i could not solve the problem but i asked someone to help, he provided the solution by using XOR(^), but could not explain for me to understand it.

For Boolean values, they mean the same thing - although there's a compound assignment operator for XOR: x ^= y; There's no equivalent compound assignment operator for inequality. As for why they're both available - it would be odd for XOR not to be available just because it works the same way as inequality. It should logically be there, so it is.

2014年3月26日 · I have the following piece of Java code and while debugging in Eclipse, Windows 7, the variable 'xoredChar' shows no value at all, not null, not '', nothing. char xoredChar = (char) (stringA.charAt(j)^stringB.charAt(j)); Why is that? I need to understand how can I do this xor operation between two characters in java. What am I missing?

2010年11月18日 · Never convert the XOR-ed long back to double, because there are many bit patterns that lead to NaN, +infinity and -infinity and many other sets of bit patterns that represent the same number (one cacnonical, the rest denormal, the most common ones being +0 and -0, +0e1, +0e2, etc)
