构造器详细资料

StringUtils

public StringUtils()

方法详细资料

isEmptys

public static boolean isEmptys(String[] array)

判断String数组是否为空

弱判断，只确定数组中第一个元素是否为空

参数:

array - 要判断的String[]数组

返回:

String数组长度==0或者第一个元素为空（true）

isNotEmptys

public static boolean isNotEmptys(String[] array)

确认String数组不为空

弱判断，只确定数组中第一个元素是否为空

参数:

array - 要判断的String[]数组

返回:

String数组长度==0或者第一个元素为空（true）

replace

public static String replace(String str,
                             String replacedStr,
                             int start,
                             int end)

替换字符串-根据索引

参数:

str - 原始字符串

replacedStr - 替换字符串

start - 开始索引，包括此索引

end - 结束索引，不包括此索引（结束索引==开始索引：将在开始索引处插入替换字符串）

返回:

替换后的字符串

deleteFirstEqualString

public static String deleteFirstEqualString(CharSequence str,
                                            CharSequence prefix)

                                           CharSequence suffix)

删除尾部相等的字符串

参数:

str - 需要处理的字符串

suffix - 条件

返回:

删除后的字符串

deleteFirstLastEqualString

public static String deleteFirstLastEqualString(String str,
                                                String firstStr,
                                                String lastStr)

删除前后相等字符串

参数:

str - 需要处理的字符串

firstStr - 开始字符串

lastStr - 末尾字符串

返回:

删除后的字符串

deleteFirstLastString

public static String deleteFirstLastString(String str,
                                           int length)

删除前后字符串

参数:

str - 需要处理的字符串

length - 删除长度

返回:

删除后的字符串
