I'm a begginer in java I have 

```
packet=090209153038020734.0090209153039020734.0 

```

like this I want to split this string and store into an array like two strings:

```
1) 090209153038020734.0
2) 090209153039020734.0

```

I have done like this:

```
String packetArray[] = packets.split(packets,Constants.SF); 

```

Where:
 Constants.SF=0x01.

But it won't work.

Please help me.
