valueOf(String name) |
返回带有指定名称的该类型的枚举常量。
字符串必须与用于声明该类型的枚举常量的
标识符完全匹配。(不允许有多余
的空格字符。)
|
static StandardCopyOption[] |
values() |
按照声明该枚举类型的常量的顺序, 返回
包含这些常量的数组。该方法可用于迭代
常量, 如下所示:
for (StandardCopyOption c : StandardCopyOption.values()) System.out.println(c); |
public static final StandardCopyOption REPLACE_EXISTING
public static final StandardCopyOption COPY_ATTRIBUTES
public static final StandardCopyOption ATOMIC_MOVE
public static StandardCopyOption[] values()
for (StandardCopyOption c : StandardCopyOption.values()) System.out.println(c);
public static StandardCopyOption valueOf(String name)
name - 要返回的枚举常量的名称。IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量NullPointerException - 如果参数为空值
