CharSequenceUtil

public CharSequenceUtil()

CharSequenceUtil instances should NOT be constructed in standard programming.

This constructor is public to permit tools that require a JavaBean instance to operate.

方法详细资料

subSequence

public static CharSequence subSequence(CharSequence cs,
 int start)

Returns a new CharSequence that is a subsequence of this sequence starting with the char value at the specified index.

This provides the CharSequence equivalent to String.substring(int). The length (in char) of the returned sequence is length() - start, so if start == end then an empty sequence is returned.

参数:

cs - the specified subsequence, null returns null

start - the start index, inclusive, valid

返回:

a new subsequence, may be null

抛出:

IndexOutOfBoundsException - if start is negative or if start is greater than length()
