isPrimitive

public static boolean isPrimitive(Object obj)

判断一个对象是否是基本类型或基本类型的封装类型

isNotBlank

public static boolean isNotBlank(CharSequence cs)

Whitespace is defined by Character.isWhitespace(char).

 StringUtils.isNotBlank(null)      = false
 StringUtils.isNotBlank("")        = false
 StringUtils.isNotBlank(" ")       = false
 StringUtils.isNotBlank("bob")     = true
 StringUtils.isNotBlank("  bob  ") = true
 

从以下版本开始:

2.0, 3.0 Changed signature from isNotBlank(String) to isNotBlank(CharSequence)

return

true if the CharSequence is not empty and not null and not whitespace only

参数

the CharSequence to check, may be null

isBlank

public static boolean isBlank(CharSequence cs)

Checks if a CharSequence is empty (""), null or whitespace only.

Whitespace is defined by Character.isWhitespace(char).

从以下版本开始:

2.0, 3.0 Changed signature from isBlank(String) to isBlank(CharSequence)

return

true if the CharSequence is null, empty or whitespace only

the CharSequence to check, may be null

length

public static int length(CharSequence cs)

Gets a CharSequence length or 0 if the CharSequence is null.

从以下版本开始:

2.4, 3.0 Changed signature from length(String) to length(CharSequence)
