  1. what is the java keyword that is used to declare class variables?

  2. Akshar Srinivasan

    I found this very easy than my text book

  3. What is the use of random()?

    • random() gives a random number between 0 and 1
      Return type: double
      Syntax: Math.random( );

      To get any random number between ‘a’ and ‘b’ use: a+ (Math.random()*(b-a))
      Example: for a random number between 2 and 100 : 2 + (Math.random()*(98))

  4. Q2. a) 1)new 2)static

  5. Explain
    endsWith()
    random ()

    • endsWith() checks whether a String ends with any given character or a String or not.
      Return Type: boolean
      Example 1: String s = “Java for school awesome”;
      boolean b = s.endsWith(‘e’); —-> b will contain ‘true’

      Example 2: String s = “Java for school awesome”;
      boolean b = s.endsWith(“some”); —-> b will contain ‘true’

      Example 3: String s = “Java for school awesome!”;
      boolean b = s.endsWith(‘e’); —-> b will contain ‘false’ because now the string ends with ‘!’

      random() gives a random number between 0 and 1
      Return type: double
      Syntax: Math.random( );

      To get any random number between ‘a’ and ‘b’ use: a+ (Math.random()*(b-a))
      Example: for a random number between 2 and 100 : 2 + (Math.random()*(98))

    CAn you please tell me
    c) What is the difference between subscript and subscripted variable
    ii) double pattern(double x, double n) with two double arguments and returns the sumof the series,

    S = xn+ x −1+ xn−2+⋯+ x2…+ x1
    and last program we have do with help of sorting bubble sort

    • Hello Vineet,

      Regarding question 1 (c):

      Subscripts are the index numbers of an array, and an array element is a subscripted variable.
      Example: In the array: int A[] = new int [5];
      The subscripts are 0, 1, 2, 3, 4 i.e. 0 – 4 and the elements A[0], A[1], A[2], A[3], A[4] are the subscripted variables.

      Regarding question 9 (ii):

      You don’t need any second loop or any sorting technique. Just run the ‘i’ loop backwards from ‘n’ to ‘1’. So the code will be:

      double pattern(double x, double n)
      {
         double sum = 0.0;
         for(double i = n; i <= 1.0; i--)
           {
            sum = sum + x/i;
           }
         return sum;
      }
