Cleaner

Cleaner is a Java beautifier software that aims to transform ugly syntax into beautiful syntax in Java code. The program achieves this by parsing the Java code syntax using ANTLR, and subsequently printing it to the standard output. The source code is included in the software, making it an open-source program.

The software works by taking Java code with less-than-perfect syntax, transforming it and making it more readable. For instance, a code snippet like:

```java
public void foo(String bar)
{
for(int x=0; x < 9; x++ )
{
System.out.println ("X = " + x);
}
}
```

will become:

```java
public void foo( String bar )
{
for ( int x = 0; x < 9; x++ )
{
System.out.println( "X = " + x );
}
}
```

Users can run the program after compiling by entering `$ java -classpath cleaner.jar:lib/antlr.jar cleaner.Cleaner < some-file >.` in their terminal.

Overall, Cleaner is an excellent program for Java developers who want to improve their Java coding style without much effort. The software is easy to use, and its open-source nature will likely prove appealing to many users.
