  1. Kisi ke teacher ne koi hint di haii kyaa ki konse programs aa skte hai ya aane vale haii??👀

  2. Sir programming me bht prblm hota h ekdam hota hi nhi h please bataye na kuch trick sirf input and printing karleta hu

  3. Anyone class 12 student who could please help me with a doubt…I am in class 10… What if the boards percentage don't take science as best five…If I get decent in science without considering it as the best five…can I get the science stream 😭???? Can somebody please lemme know…🙏🏻🙏🏻

  4. @Amplify Learning with Alok

    Sir please upload a video on recursion output where printing takes place on LIFO principle

  5. Keyword and their Usage
    1. abstract : Specifies that a class or method will be implemented later, in a subclass
    2. assert: Assert describes a predicate placed in a java program to indicate that the developer thinks that the predicate is always true at that place.
    3. boolean: A data type that can hold True and False values only
    4. break : A control statement for breaking out of loops.
    5. byte: A data type that can hold 8-bit data values
    6. case : Used in switch statements to mark blocks of text
    7.catch : Catches exceptions generated by try statements
    8.char : A data type that can hold unsigned 16-bit Unicode characters
    9.class: Declares a new class
    10.continue : Sends control back outside a loop 
    11.default : Specifies the default block of code in a switch statement : Starts a do-while loop
    13.double : A data type that can hold 64-bit floating-point numbers
    14.else : Indicates alternative branches in an if statement 
    15.enum : A Java keyword is used to declare an enumerated type. Enumerations extend the base class.
    16.extends : Indicates that a class is derived from another class or interface : Indicates that a variable holds a constant value or that a method will not be overridden
    18.finally : Indicates a block of code in a try-catch structure that will always be executed
    19.float : A data type that holds a 32-bit floating-point number 
    20.for : Used to start a for loop
    21.if: Tests a true/false expression and branches accordingly
    22.implements : Specifies that a class implements an interface 
    23.import : References other classes
    24.instanceof : Indicates whether an object is an instance of a specific class or implements an interface : A data type that can hold a 32-bit signed integer 
    26.interface : Declares an interface
    27.long A data type that holds a 64-bit integer
    28.native : Specifies that a method is implemented with native (platform-specific) code : Creates new objects
    30.null : This indicates that a reference does not refer to anything 
    31.package Declares a Java package
    32.private An access specifier indicating that a method or variable may be accessed only in the class it’s declared in
    33.protected An access specifier indicating that a method or variable may only be accessed in the class it’s declared in (or a subclass of the class it’s declared in or other classes in the same package)
    34.public An access specifier used for classes, interfaces, methods, and variables indicating that an item is accessible throughout the application (or where the class that defines it is accessible)
    35.return Sends control and possibly a return value back from a called method 
    36.short A data type that can hold a 16-bit integer 
    37static : Indicates that a variable or method is a class method (rather than being limited to one particular object)
    38.strictfp A Java keyword is used to restrict the precision and rounding of floating-point calculations to ensure portability.
    39.super Refers to a class’s base class (used in a method or class constructor) 
    40.switch A statement that executes code based on a test value 
    41.synchronized Specifies critical sections or methods in multithreaded code
    42.this Refers to the current object in a method or constructor
    43.throw Creates an exception 
    44.throws Indicates what exceptions may be thrown by a method 
    45.transient Specifies that a variable is not part of an object’s persistent state
    46.try Starts a block of code that will be tested for exceptions 
    47.void Specifies that a method does not have a return value
    48.volatile This indicates that a variable may change asynchronously
    49.while Starts a while loop

  6. Easiest way to reverse a num using recursion
    int reverse(int v)
    int l = (" " + v).length( );
    if ( v < 10)
    return v
    return v %10 * math.pow(10, l – 1) + reverse (v / 10)

  7. Sir you are like god for ICSE and ISC students because there is no other dedicated channels on whole youtube like yours.I am following your channel since my 9th class (year 2019) and this year I am appearing for my 12th boards(year 2023).Your channel helped me a lot during my four years' journey.I strongly recommend your channel to all upcoming juniors.You always make every concept very simple and straightforward in few minutes.I am very fascinated by your teaching style.My best wishes that you gain more and more subscribers and students in the upcoimg time.Once again,thank u for all your videos which helped ICSE and ISC students a lot.🙏🙏🙏🙌🙌🙌👏👏👏

  8. Please make video one shot on theory questions solving please please we'll watch 2-3 videos throughout the day please sir upload video

  9. Sir ek aisi video bhi bandaijiye jisme saari 1 mark wali important theory ho please

  10. Thank You Sir . Much needed video , my all doubts are cleared with this type of program

  11. Sir class 10th ka chemistry ka important topics aur paper pattern wala video jaldi dhal dijiye plz🙏🙏

  12. Sir isme ham log 'this' keyword ka use kr skte the kya 'find reverse' function me

  13. Sir I've been watching your videos since 4 years now ❤ you are one of the teachers who provide us with top quality Content, this was just to say thankyou ❤

  14. I got one more logic for reversing numbers :
    int rev(int n) {

    if (n==0)

    return 0;


    return (int)(n/Math.pow(10,((""+n).length() – 1))) + rev(n % (int)Math.pow(10,((""+n).length() – 1))) * 10;

    This also works correctly, without wrapper class, but thanks alok sir for the wrapper class trick, it was good.

  15. Sir important number programs bata diye…Aur sir buffered reader se marks zyada milte hai kyaa?

  16. Sir can't we take rb1 variable instead of rb2 and then take each element from A array and invoke reverse function and then put elements in rb1 ?
