Write File Using FileOutputStream with new Jdk 1.7 try block feature

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

public class WriteFileExample2 {
public static void main(String[] args) {

File file = new File("d:/java4.txt");
String content = "This is the text content";

//New jdk 1.7 feature
try (FileOutputStream fop = new FileOutputStream(file)) {

// if file doesn't exists, then create it
if (!file.exists()) {
file.createNewFile();
}

// Get the content in bytes
byte[] contentInBytes = content.getBytes();

fop.write(contentInBytes);
fop.flush();
fop.close();

System.out.println("Done");

} catch (IOException e) {
e.printStackTrace();
}
}
}

Write File Using FileOutputStream

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

public class WriteFileExample {
public static void main(String[] args) {

FileOutputStream fop = null;
File file;
String content = "This is the text content";

try {

file = new File("d:/java3.txt");
fop = new FileOutputStream(file);

// if file doesn't exists, then create it
if (!file.exists()) {
file.createNewFile();
}

// Get the content in bytes
byte[] contentInBytes = content.getBytes();

fop.write(contentInBytes);
fop.flush();
fop.close();

System.out.println("Done");

} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (fop != null) {
fop.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
}

Write File Using FileWriter

import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

public class WriteFileEx {

public static void main(String args[]) {

String data="THIS IS THE DATA TO WRITE IN THE FILE";

File file = new File("d:/java2.txt");
FileWriter fr = null;
try {
fr = new FileWriter(file);
fr.write(data);
} catch (IOException e) {
e.printStackTrace();
}finally{
try {
fr.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

}

Write File Using Files Class

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

//Files class is available from 1.7
public class UsingFilesClass {

public static void main(String args[]) {

String data = "SOME DATA";
try {
Files.write(Paths.get("d:/java1.txt"), data.getBytes());
System.out.println("Done");
} catch (IOException e) {
e.printStackTrace();
}
}
}

Write File Using BufferedWriter,FileWriter

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

public class BufferedWriterExample {
public static void main(String[] args) {
try {

String content = "This is the content to write into file";

File file = new File("d:/java.txt");

// if file doesn't exists, then create it
if (!file.exists()) {
file.createNewFile();
}

FileWriter fw = new FileWriter(file.getAbsoluteFile());
BufferedWriter bw = new BufferedWriter(fw);
bw.write(content);
bw.close();

System.out.println("Done");

} catch (IOException e) {
e.printStackTrace();
}
}
}
