How to create temporary file in java?.

 Creating a temporary file in Java is straightforward. There are two static methods named createTempFile in the Java File class, one that takes two arguments, and another that takes three arguments. I created the test class shown below to demonstrate how to create a Java temporary file.

Here's the source code for temporary file example:

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

public class JavaTemporaryFiles
{
public static void main(String[] args) throws IOException
{
String prefix = "abc";
String suffix = ".tmp";

// this temporary file remains after the jvm exits
File tempFile = File.createTempFile(prefix, suffix);
System.out.format("Canonical filename: %s\n", tempFile.getCanonicalFile());
}}
