how binary search works in java?
159422
Binary Search in Java is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array. It works only on a sorted set of elements. To use binary search on a collection, the collection must first be sorted.

Bitwise XOR (exclusive or) "^" is an operator in Java that provides the answer '1' if both of the bits in its operands are different, if both of the bits are same then the XOR operator gives the result '0'. XOR is a binary operator that is evaluated from left to right.

Bit & Byte A binary digit is called a bit. There are two possible states in a bit, usually expressed as 0 and 1. A series of eight bits strung together makes a byte, much as 12 makes a dozen. With 8 bits, or 8 binary digits, there exist 2^8=256 possible combinations.

Second difference between equals and == operator is that, == is used to check reference or memory address of the objects whether they point to the same location or not, and equals() method is used to compare the contents of the object e.g. in case of comparing String its characters, in case of Integer it's their ...

HashMaps use an array in the background. Each element in the array is another data structure (usually a linked list or binary search tree). The HashMap uses a function on the key to determine where to place the key's value in the array.

The main difference between Binary file and text file is the format of contents within the the file. ... Binary file contains the data in the form of 0 and 1(series of binary values) and text files contains the data in the form of stream of characters.In general binary files are identified as executable files.

The binary system on computers uses combinations of 0s and 1s. In everyday life, we use numbers based on combinations of the digits between 0 and 9. This counting system is known as decimal, denary or base 10.

Equals(b) or a == b ? The Equals() and == operator are used for comparison and both returns the boolean value (true/false). For Value Type == and Equals() works in the same way, both compare two object by value. ... Equals(b) returns true , because in this case both compare two object by value.

1) use == to compare primitive e.g. boolean, int, char etc, while use equals() to compare objects in Java. 2) == return true if two reference are of same object. Result of equals() method depends on overridden implementation.

A computer uses the binary numeral system which is also known as base 2. And in this system, there are only two digits, 1 and 0. ... So, the decimal number system uses ten different digits (from 0 to 9); but the binary number system uses only two different digits (0 and 1).

In general both equals() and “==” operator in Java are used to compare objects to check equality but here are some of the differences between the two: ... In simple words, == checks if both objects point to the same memory location whereas . equals() evaluates to the comparison of values in the objects.

To subtract binary numbers, simply align the 2 numbers and subtract as you would a regular problem. To subtract with the complement method, align the numbers and, if necessary, add zeros to the front of the second number to give it has an equal amount of digits.

A binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system. The binary code assigns a pattern of binary digits, also known as bits, to each character, instruction, etc.

Two objects will be only equal if they have same identity. It does not matter if they have same content or not. The fact can be determined by === operator. Primitives are compared by value, they don't have individual identities.
