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)!
