    // Method ables to find the sequence of characters(am) therefore it
    // generates boolean type true
    System.out.println("Method returns true here:  " + "'" + result + "'");
    result = str1.contains(char1);
    System.out.println();
    // Method ables to fing the symbol underscore(_) therefore it generates
    // boolean type true"
    System.out.println("'true' is returned:    " + "'" + result + "'");

    System.out.println();
    str2 = " hare ram1 hare ram, hare krishna hare ram ";
