<p>Is it possible for Eclipse to read stdin from a file?</p>

Pure Java
You can redirect System.in with a single line of code:
```
```
System.setIn(new FileInputStream(filename));
```
```
See
System.setIn()
.
Eclipse config
In Eclipse 4.5 or later, the launch configuration dialog can set System.in to read from a file. See
the announcement here
