Java Example - Set File Read Only

The following example demonstrates using the file.setReadOnly() and file.canWrite() methods of the File class to set the file read-only:

/*
 author by w3cschool.cc
 Main.java
 */import java.io.File;public class Main {
   public static void main(String[] args) {
      File file = new File("C:/java.txt");
      System.out.println(file.setReadOnly());
      System.out.println(file.canWrite());
   }}

The output result of the above code is:

true
false

The above is the Java example - setting the read-only content of the file. For more related content, please pay attention to the PHP Chinese website (www.php.cn)!
