A convenience method to set the owner's write permission for this abstract pathname.

Usage

From source file:Main.java

public static void main(String[] args) {
    File f = new File("C:/test.txt");
    boolean bool = f.setWritable(true);

    System.out.println("setWritable() succeeded?: " + bool);

    bool = f.canWrite();/*from  w  ww.  j  av a  2 s.c om*/

    System.out.print("Is file writable?: " + bool);

}

From source file:ROW.java

public static void main(String[] args) {
    File filespec = new File("c:\text.txt");

    if (filespec.setWritable(false))
        System.out.println(filespec + " made read-only");
    else//w w w .j  a  v  a2 s .c  om
        System.out.println("Permission denied");
    if (filespec.setWritable(true))
        System.out.println(filespec + " made writable");
    else
        System.out.println("Permission denied");

    System.out.println(filespec + " is currently " + (filespec.canWrite() ? "writable" : "read-only"));
}

From source file:Main.java

public static void main(String[] args) {
    File f = new File("test.txt");

    // set writable to false
    f.setWritable(false);

    // returns boolean
    boolean bool = f.canWrite();

    System.out.println("Can write to test.txt: " + bool);
}

From source file:FileAttributesDemo.java

public static void main(String[] args) throws IOException {
    // Create a new file, by default canWrite=true, readonly=false

    }
    file.createNewFile();
    System.out.println("Before. canWrite?" + file.canWrite());

    // set to read-only, atau canWrite = false */
    file.setWritable(false);
    System.out.println("After. canWrite?" + file.canWrite());
}

From source file:Main.java

public static void main(String[] args) throws Exception {
