"StudentId": 2,

var array2={
"MarksList": [
{
"StudentId": 1,
"subject": "FUNDAMENTALS OF INFORMATION TECHNOLOGY",
"marks": 17,
"subject": "COMPUTER ORGANIZATION",
"marks": 25,
"subject": "ENGLISH",
"marks": 20

"subject": "FUNDAMENTALS OF INFORMATION TECHNOLOGY",
"marks": 17,
"subject": "COMPUTER ORGANIZATION",
"marks": 25,
"subject": "ENGLISH",
"marks": 20
