28+
<groupId>com.github.zrdj</groupId>

<version>0.2.0</version>
31+
</dependency>
32+
```
33+
34+
## Motivation
35+
36+
This is just a fun project to reimplement the horrible file walking implementation from the JDK, trying to combine the
37+
two Java APIs of `File.listFiles()` and `Files.walkFileTree()` into a new API using Java's new `Stream<T>` feature of
38+
version 8.
39+
40+
To search for files simply start with the static method `Search.search()` and search for executable (.exe) files ...
41+
42+
... not **recursively** using the **Path API**
43+
44+
```java
45+
import static com.github.zrdj.java.filesearch.Search.search;
46+
47+
public void doSomeFileSearchStuff() {
48+
final List<Path> executables = search().directory("S:\Earch\Path").notRecursively().byPath()
49+
.stream()
50+
.filter(p -> p.getFileName().toString().endsWith(".exe"))
51+
.collect(Collectors.toList());
52+
// do something with found files
53+
}
54+
```
55+
56+
... or **recursively** using the **Path API**
57+
58+
```java
59+
import static com.github.zrdj.java.filesearch.Search.search;
60+
61+
public void doSomeFileSearchStuff() {
62+
final List<Path> executables = search().directory("S:\Earch\Path").recursively().byPath()
63+
.stream()
64+
.filter(p -> p.getFileName().toString().endsWith(".exe"))
65+
.collect(Collectors.toList());
66+
// do something with found files
67+
}
68+
```
69+
70+
... or **not recursively** using the **File API**
71+
72+
```java
73+
import static com.github.zrdj.java.filesearch.Search.search;
74+
75+
public void doSomeFileSearchStuff() {
76+
final List<File> executables = search().directory("S:\Earch\Path").notRecursively().byFile()
77+
.stream()
78+
.filter(f -> f.getName().endsWith(".exe"))
79+
.collect(Collectors.toList());
80+
// do something with found files
81+
}
82+
```
83+
84+
... or **recursively** using the **File API**
85+
86+
```java
87+
import static com.github.zrdj.java.filesearch.Search.search;
88+
89+
public void doSomeFileSearchStuff() {
90+
final List<File> executables = search().directory("S:\Earch\Path").recursively().byFile()
91+
.stream()
92+
.filter(f -> f.getName().endsWith(".exe"))
93+
.collect(Collectors.toList());
94+
// do something with found files
95+
}
96+
```
