Create class Document with below attributes
2+
3+
id - int
4+
title - String
5+
folderName - String
6+
pages - int
7+
8+
Write getters, setters and parameterized constructor as required.
9+
10+
Create class Solution with main method.
11+
12+
Implement static method - docsWithOddPages in Solution class.
13+
14+
This method will take array of Document objects and return another array with Document objects which has odd number of pages.
15+
16+
This method should be called from main method and display values of returned objects as shared in the sample (in ascending
17+
order of id attribute).
18+
19+
Before calling this method, use Scanner object to read values for four Document objects referring attributes in the above
20+
sequence.
21+
22+
Next call the method and display the result.
23+
24+
Consider below sample input and output:
25+
26+
Input:
27+

28+

29+

40+

41+
misc
42+

43+
44+
45+
Output (each line has values separated by single space):
46+
2 question1 exams 55
47+
3 question2 exams 45
48+
49+
50+
51+
Note on using Scanner object:
52+
Sometimes scanner does not read the new line character while invoking methods like nextInt(), nextDouble() etc.
53+
Usually, this is not an issue, but this may be visible while calling nextLine() immediately after those methods.
54+
55+
Consider below input values:
56+
22
57+
hello
58+
59+
Referring below code:
60+
61+
Scanner sc = new Scanner(System.in);
62+
int x = sc.nextInt();
63+
String str = sc.nextLine(); -> here we expect str to have value hello. Instead it may be """".
64+
65+
If above issue is observed, then it is suggested to add one more explicit call to nextLine() after reading numeric value.
