How do I add files to my folder? java

Question

My program is creating files and I'm needing to put them in a specific folder. Not sure of the process. Thanks

String path = "C:\\Users\\Blah\\Desktop\\blahblah\\FOLDER";
File bfFolder = new File (path);
bfFolder.mkdir();

for (int a = 0; a < 20; a++) {
    try (DataOutputStream dataO = new DataOutputStream(new FileOutputStream("file" + " a"))) {

Answer 1

You can pass a File to new FileOutputStream() . To create a new File inside the directory you created, pass the parent directory and the filename to the constructor:

// This will refer to C:\Users\Blah\Desktop\blahblah\FOLDER\name.txt
File myFile = new File(bfFolder, "name.txt");
try(FileOutputStream fStream = new FileOutputStream(myFile);
    DataOutputStream data0 = new DataOutputStream(fStream)) {

检出Files.copy（），这是执行所需操作的快速方法。
