Operators and For Loop

 Bitwise operator -


Bitwise operators ko istemal karke aap integers ke alag-alag bits par operations kar sakte hain. Java mein, kuch aise bitwise operators hote hain jo aapko numbers ke alag-alag bits ko manipulate karne aur shifting aur masking jaise alag-alag operations perform karne ki anumati dete hain.

Yahan par Java mein common bitwise operators hain:

AND (&): Ye corresponding bits ke beech mein bitwise AND operation perform karta hai. Result bit sirf tab 1 hoga jab dono input bits 1 honge.

OR (|): Ye corresponding bits ke beech mein bitwise OR operation perform karta hai. Result bit 1 hoga agar kam se kam ek input bit 1 hoga.

XOR (^): Ye corresponding bits ke beech mein bitwise XOR (exclusive OR) operation perform karta hai. Result bit tab 1 hoga jab input bits alag honge.

NOT (~): Ye ek integer ke individual bits par bitwise NOT operation perform karta hai, jiske wajah se saare bits flip ho jate hain (1s 0s ban jaate hain aur vice versa).

Left Shift (<<): Ye ek integer ke bits ko left mein di gayi positions se shift karta hai. Naye bits jo right side par aate hain, unko zero se fill kiya jata hai.

Right Shift (>>): Ye ek integer ke bits ko right mein di gayi positions se shift karta hai. Leftmost bits mein sign bit (signed numbers ke liye) ya phir zero (unsigned numbers ke liye) fill kiya jata hai.

Unsigned Right Shift (>>>): Right shift operator ke jaisa hai, lekin yahan leftmost bits ko zero se fill kiya jata hai, chaahe number ka sign kaisa bhi ho.

Ye bitwise operators operands ke individual bits par kaam karte hain, jo integers ya dusre numeric data types ho sakte hain. Ye aksar low-level operations ke liye istemal hote hain jaise ki code ko optimize karna, hardware ke saath kaam karna, ya bit-packed data structures ke andar individual flags ko set ya clear karna.

Block vs Inline Elements In HTML

  Block: Block element always start in New Line  Block element always start in new line occupy complete width available  Example: h2, p, div Inline Element: They do not start in new line occuply width as much required  Example: img, anchor a,span There are no different between div and span, only difference is div is block element and span is Inline, it will help you to group your content or elements

Find Unique Number in Array Java , XOR

 Question:  WAP to find unique number in Array Java package aRray ; import java . util .*; public class practicalArray { public static void main ( String [] args ) { Scanner scan = new Scanner ( System . in ) ; // Step 1: Input size of the array from the user int size = scan . nextInt () ; // Step 2: Create an integer array of the specified size int [] arr = new int [ size ] ; // Step 3: Initialize 'res' with the first element of the array int res = arr [ 0 ] ; // Step 4: Loop to read array elements and find the unique number for ( int i = 1 ; i < size ; i ++ ) { // Read an integer from the user and store it in the array arr [ i ] = scan . nextInt () ; // Step 5: Use XOR (^) operation to find the unique number res = res ^ arr [ i ] ; } // Step 6: Print the unique number System . out . print...
