Usage

From source file:Main.java

public static void main(String[] args) {
    File file = new File("Main.java");
    Long lastModified = file.lastModified();
    Date date = new Date(lastModified);
    System.out.println(date);//w  w w .java  2 s  .  c o  m
}

From source file:Main.java

public static void main(String[] args) {
    File file = new File("C:/ReadText.txt");
    System.out.println(file.lastModified());

    System.out.println(file.setLastModified(new Date().getTime()));
    System.out.println(new Date(file.lastModified()));
}

From source file:MainClass.java

public static void main(String[] args) {
    // Create an object that is a directory
    File myDir = new File("C:/Java_Dev");
    System.out.println(new Date(myDir.lastModified()));
}

From source file:Main.java

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

    File file = new File("filename");

    long modifiedTime = file.lastModified();
    // 0L is returned if the file does not exist

    long newModifiedTime = System.currentTimeMillis();
    boolean success = file.setLastModified(newModifiedTime);
    if (!success) {
        // operation failed.
    }// w  w  w.  j  a v  a2 s.co  m
}
