  9. 2((i))Write the Java expression for (p + q)22 marks
  10. 2((ii))Evaluate the expression when the value of x = 2:
    x = x ++ + ++ x + x    2 marks
  11. 2((iii))The following code segment should print “You can go out” if you have done
    your homework (dh) and cleaned your room(cr). However, the code has errors.
    Fix the code so that it compiles and runs correctly.
    boolean dh = True;
    boolean cr= true;
    if (dh && cr)

    irrespective of any non zero values are given. Name the error. How the program
    can be modified to get the correct answer?

    { double a;
    a = ½ * b * h;
    System.out.println(“Area=”+a); }    2 marks
  13. 2((vi))Write the output of the following String methods:
    (a) "ARTIFICIAL ".indexOf('I' )
    (b) “DOG and PUPPY”. trim().length()    2 marks

  15. 2((x))int P [ ]={ 12,14,16,18}; int Q[ ]={ 20,22,24};
    Place all elements of P array and Q array in the array R one after the other.
    (a) What will be the size of array R [ ] ?
    (b) Write index position of first and last element?
    (Answer any four questions from this Section.)
    The answers in this section should consist of the programs in either BlueJ environment or any
    program environment with java as the base.
    Each program should be written using variable description / mnemonic codes so that the logic of the
    program is clearly depicted.
    Flowcharts and algorithms are not required.    2 marks
