In below example we will create temporary file and write some content in it and verify by opening this file from temporary location:

package com.javahonk;

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

public class CreateTempFileJava {

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

			// Creates an empty file in the default temporary-file directory,
			// using the given prefix and suffix to generate its name
			File tempFile = File.createTempFile("temproryFileByJava", ".tmp");
			System.out.println(tempFile.getAbsolutePath());
			FileWriter fw = new FileWriter(tempFile.getAbsoluteFile());
			BufferedWriter bw = new BufferedWriter(fw);
			for (int i = 0; i < 10; i++) {
				bw.write("Write to temp file");
				bw.newLine();
			}
			bw.close();

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