create a temporary file with a specified name in java

问题

I have a Byte[] array that i want to put it's content into a temporary file .

I have tryied to do it like this

try {
            tempFile = File.createTempFile("tmp", null);
            FileOutputStream fos = new FileOutputStream(tempFile);
            fos.write(sCourrier.getBody());
        } catch (IOException e) {
            e.printStackTrace();
        }

but i want that I specify the filename by myself so not generated by the jvm

回答1:

You can directly give the location and file name or You can access local filesystem and find the temp directory

 String tempDir=System.getProperty("java.io.tmpdir");

you can use temp directory and your custom file name.

public static void main(String[] args) {
    try {
        String tempDir=System.getProperty("java.io.tmpdir");
        String sCourrier ="sahu";
        File file = new File(tempDir+"newfile.txt");
        FileOutputStream fos = new FileOutputStream(file);
        fos.write(sCourrier.getBytes());
    } catch (IOException e) {
        e.printStackTrace();
    }
