How To Create + Write Temporary File In Java

If you are working on the file operations, it is obvious that you have to use the temporary file concept for the file transfer activities. When you download or transfer a file from one location to another, a temporary file is created and then data transferred to the location. Once the entire data is transferred, then temporary file can be deleted and moved to the original file. This operation can be done in the Java File IO package as shown in this example.

This example shows how to create a temporary file and writing content to the file. By default, the temporary file will be created in the “temp” folder of your operating system.

Create + Write Temp File Example



public class CreateTempFileExample {
	public static void main(String[] args) {
		try {
			//Create temp file
			File tempFile = File.createTempFile("javabeat-temp-file", ".tmp");
			System.out.println("Temp File Name : " + tempFile.getAbsolutePath());
			BufferedWriter bufferedReader = new BufferedWriter(new FileWriter(tempFile));

			//Write to tem file
    	    bufferedReader.write("This is a test tem file creating and writing example!!");

		} catch (IOException e) {
