I have a text file "test.txt" with the following content

```
********************
Hi
This is ABC
I learning JAVA and would like to expertize in it.
I joined Stackoverflow today.
********************

```

My requirement is to make the line #4 - I joined Stackoverflow today. as the first line in test.txt so that the file content is as follows:

```
********************
I joined Stackoverflow today.
Hi
This is ABC
I learning JAVA and would like to expertize in it.
I joined Stackoverflow today.
********************

```

Can this be done via code, as I am trying to use various Java Utils, but I am unable to make the line move to the first place.
