+# Java Reader and Write Files
+
+Example Application: Reader_(FileReader)_ and Write_(FileWriter)_ files.
+
+## Read File
+
+Imports
+
+```java
+import java.io.BufferedReader;
+import java.io.File;
+import java.io.FileReader;
+import java.io.IOException;
+```
+
+Check file exists.
+
+:warning: Creates a new File instance by converting the given pathname string into an abstract pathname. If the given string is the empty string, then the result is the empty abstract pathname.
+
+```java
+File file = new File(FILE);
+
+if (file.exists()) {
+	//TODO
+} else {
+	//TODO
+}
+```
+
+Read file
+
+```java
+String FILE = "YOUR_LOG.log";
+
+FileReader reader = new FileReader(FILE);
+BufferedReader buffer = new BufferedReader(reader);
+
+String line = null;
+
+while ((line = buffer.readLine()) != null) {
+	//TODO
+	System.out.printf("%s\n", line);
+}
+
+```
+
+:warning: 
+
+```java
+buffer.close();
+```
+
+
+## Write File
+
+Imports
+
+```java
+import java.io.BufferedWriter;
+import java.io.File;
+import java.io.FileWriter;
+import java.io.IOException;
+```
+
+Check file exists
+
+:warning: Creates a new File instance by converting the given pathname string into an abstract pathname. If the given string is the empty string, then the result is the empty abstract pathname.
+
+```java
+String FILE = "YOUR_LOG.log";
+
+File file = new File(FILE);
+
+if (file.exists()) {
+	//TODO
+} else {
+	//TODO
+}
+```
+
+Write File
+
+:warning: _Need add **throws declaration** or surround with **try/catch**;_
+
+```java
+String content = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";
+
+String FILE = "YOUR_LOG.log";
+FileWriter writer = new FileWriter(FILE);
+BufferedWriter buffer = new BufferedWriter(writer);
+
+buffer.write(content);
+
+System.out.println("Success! You file is saved!");
+buffer.close();
+```
