// This method can only add text to the file once, and overwrite the original text if (! File. exists (PATH) {// if the target text does not exist, create a new file string createtext = "Hello and welcome" + environment. newline; // text content, followed by a line feed command file. writealltext (path, createtext, encoding. utf8); // write content}

// If the target text exists, use the following method to add the text, which does not overwrite the original content and only append the text.
