Notes


                        That  the  array  must  be  sorted  before  invoking  binarySearch().  If  it  is  not  sorted,  the  results  are
                        undefined.

            Sometimes, we may come across certain problems which require executing some tasks repeatedly, but with different
            input values. This is exactly the situation where we use user-defined methods.
            Let us take an example.
            Write a program in Java to print the sum and average of two marks 10 and 30 obtained by a student. Also, the same
            operation is required to be done for the other student who got 20 and 35 marks.

             int m1=10, m2=30, n1=20, n2=35, sum;
             double avg;

             sum = m1+m2;
