Examples of java.nio.file.attribute.BasicFileAttributes

java.nio.file.attribute.BasicFileAttributes
Basic attributes associated with a file in a file system.
Basic file attributes are attributes that are common to many file systems and consist of mandatory and optional file attributes as defined by this interface.
Usage Example:
```
 Path file = ... BasicFileAttributes attrs = Files.readAttributes(file, BasicFileAttributes.class); 
```
@since 1.7 @see BasicFileAttributeView

    Files.setAttribute(foo, "owner:owner", zero);


    Path bar = path("/bar");
    Files.copy(foo, bar, COPY_ATTRIBUTES);


    BasicFileAttributes attributes = Files.readAttributes(bar, BasicFileAttributes.class);
    assertThat(attributes.lastModifiedTime()).isEqualTo(FileTime.fromMillis(100));
    assertThat(attributes.lastAccessTime()).isEqualTo(FileTime.fromMillis(1000));
    assertThat(attributes.creationTime()).isEqualTo(FileTime.fromMillis(10000));
    assertThat(Files.getAttribute(bar, "owner:owner")).isEqualTo(zero);


    Path baz = path("/baz");
    Files.copy(foo, baz);


    // test that attributes are not copied when COPY_ATTRIBUTES is not specified
    attributes = Files.readAttributes(baz, BasicFileAttributes.class);
    assertThat(attributes.lastModifiedTime()).isNotEqualTo(FileTime.fromMillis(100));
    assertThat(attributes.lastAccessTime()).isNotEqualTo(FileTime.fromMillis(1000));
    assertThat(attributes.creationTime()).isNotEqualTo(FileTime.fromMillis(10000));
    assertThat(Files.getAttribute(baz, "owner:owner")).isNotEqualTo(zero);
