Let's see how your algorithm works: an array of unique values: [1, 2, 3] check 1 == 1. yes, there is duplicate, assigning duplicate to true. check 2 == 3. no, doing nothing. Besides not being a lazy evaluator by evaluating both operands, I think the main characteristics of bitwise operators compare each bytes of operands like in the following example: It depends on the type of the arguments For integer arguments, the single ampersand ("&")is the "bit-wise AND" operator. When both operands of a &, ^, or | operator are of type boolean or Boolean, then the type of the bitwise operator expression is boolean. When accessing collections, Java 8 has introduced streams which perform generally better with a decent size dataset. Actually it can take more than 3 arguments.

You can instantiate a BigInteger object in several ways:. I always thought that && operator in Java is used for verifying whether both its boolean operands are true, and the & operator is used to do Bit-wise operations on two integer types. The easiest way to avoid problems is not to override the equals method, in which case each instance of the class is equal only to itself. (Floating-point values are truncated before they are assigned to the BigInteger. expression1 if boolean-expression is true; Suppose you want to assign the larger number of variable num1 and num2 to max.

Stack Overflow for Teams is moving to its own domain! Some also call it the conditional operator. 1.1 hasNext(): Returns true if the iteration has more elements. Secondly, in C-like languages, you get in the habit of simply knowing that conditionals are the first thing in the line. The spec you mention also refers to this operator as the "Ternary Conditional" which seems more informative. One possible approach is the Thompson's construction algorithm to construct a nondeterministic finite automaton (NFA), which is then made deterministic and the resulting I don't understand what the bottom one does that is wrong. & is a bitwise operator plus used for checking both conditions because sometimes we need to evaluate both condition.
