EMPTY_STRING_ARRAY

public static final String[] EMPTY_STRING_ARRAY

方法详细资料

currentDateTime

public static String currentDateTime()

weakIntern

public static String weakIntern(String sample)

Interns and returns a reference to the representative instance for any of a collection of string instances that are equal to each other. Retains weak reference to the instance, and so does not prevent it from being garbage-collected.

参数:

sample - string instance to be interned

返回:

weak reference to interned string instance

getTrimmedStrings

public static String[] getTrimmedStrings(String s)

Splits the given comma separated String. Each split value is trimmed.

参数:

s - a comma separated String, or possibly null.

返回:

the split strings, or an empty array if the given string is null.

format

public static String format(String format,
                            Object... objects)

The same as String.format(Locale.ENGLISH, format, objects).
