StringKit

public StringKit()

Method Details

trim

public static void trim(String[] args)

给定字符串数组全部做去首尾空格

Parameters:

args - 字符串数组

toString

public static String toString(Object object)

将对象转为字符串

 1、Byte数组和ByteBuffer会被转换为对应字符串的数组
 2、对象数组会调用Arrays.toString方法
 

Parameters:

object - 对象

Returns:

字符串

toString

public static String toString(Object object,
 Charset charset)

将对象转为字符串

         1、Byte数组和ByteBuffer会被转换为对应字符串的数组
         2、char[]会直接构造String
         3、对象数组会调用Arrays.toString方法
 

Parameters:

object - 对象

charset - 字符集

Returns:

字符串

toString

public static String toString(byte[] data,
 Charset charset)

解码字节码

Parameters:

data - 字符串

charset - 字符集，如果此字段为空，则解码的结果取决于平台

Returns:

解码后的字符串

toString

public static String toString(Byte[] data,
 Charset charset)

解码字节码

Parameters:

data - 字符串

charset - 字符集，如果此字段为空，则解码的结果取决于平台

Returns:

解码后的字符串

toString

public static String toString(ByteBuffer data,
 Charset charset)

将编码的byteBuffer数据转换为字符串

Parameters:

data - 数据

charset - 字符集，如果为空使用当前系统字符集

Returns:

字符串

stringFast

public static String stringFast(char[] value)

JDK8中，通过String(char[] value, boolean share)这个内部构造创建String对象。 此函数通过传入char[]，实现zero-copy的String创建，效率很高。但是要求传入的char[]不可以在其他地方修改。

Parameters:

value - char[]值，注意这个数组不可修改！！

Returns:

String

builder

public static StringBuilder builder()

创建StringBuilder对象

Returns:

StringBuilder对象

builder

public static StringBuilder builder(int capacity)

创建StringBuilder对象

Parameters:

capacity - 初始大小

Returns:

StringBuilder对象

getReader

public static StringReader getReader(CharSequence text)

获得StringReader

Parameters:

text - 字符串

Returns:

StringReader

getWriter

public static StringWriter getWriter()

获得StringWriter

Returns:

StringWriter

reverse

public static String reverse(String text)

反转字符串 例如：abcd = dcba

Parameters:

text - 被反转的字符串

Returns:

反转后的字符串

fillBefore

public static String fillBefore(String text,
 char filledChar,
 int len)

将已有字符串填充为规定长度，如果已有字符串超过这个长度则返回这个字符串 字符填充于字符串前

Parameters:

text - 被填充的字符串

filledChar - 填充的字符

len - 填充长度

Returns:

填充后的字符串

fillAfter

public static String fillAfter(String text,
 char filledChar,
 int len)

将已有字符串填充为规定长度，如果已有字符串超过这个长度则返回这个字符串 字符填充于字符串后

Parameters:

len - 填充长度

Returns:

填充后的字符串

fill

public static String fill(String text,
 char filledChar,
 int len,
 boolean isPre)

将已有字符串填充为规定长度，如果已有字符串超过这个长度则返回这个字符串

Parameters:

len - 填充长度

isPre - 是否填充在前

Returns:

填充后的字符串

fill

public static String fill(int count,
 char charVal)

输出指定长度字符

Parameters:
