Once Java installation is done properly, then you should get the following output for both the operating systems −
| S.No | OS & Description |
|---|---|
| 1 |
Windows
Java version "1.7.0_60" Java (TM) SE Run Time Environment (build 1.7.0_60-b19) Java HotSpot(TM) 64-bit Server VM (build 24.60-b09,mixed mode)
