本文整理了Java中org.apache.commons.lang3.StringUtils.isNumeric()方法的一些代码示例，展示了StringUtils.isNumeric()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。StringUtils.isNumeric()方法的具体详情如下：
包路径：org.apache.commons.lang3.StringUtils
类名称：StringUtils
方法名：isNumeric
[英]Checks if the CharSequence contains only Unicode digits. A decimal point is not a Unicode digit and returns false.
null will return false. An empty CharSequence (length()=0) will return false.
Note that the method does not allow for a leading sign, either positive or negative. Also, if a String passes the numeric test, it may still generate a NumberFormatException when parsed by Integer.parseInt or Long.parseLong, e.g. if the value is outside the range for int or long respectively.
StringUtils.isNumeric(null) = false
StringUtils.isNumeric("") = false
StringUtils.isNumeric(" ") = false
StringUtils.isNumeric("123") = true
StringUtils.isNumeric("\u0967\u0968\u0969") = true
StringUtils.isNumeric("12 3") = false
StringUtils.isNumeric("ab2c") = false
StringUtils.isNumeric("12-3") = false
StringUtils.isNumeric("12.3") = false
StringUtils.isNumeric("-123") = false
StringUtils.isNumeric("+123") = false[中]检查CharSequence是否仅包含Unicode数字。小数点不是Unicode数字，返回false。
null将返回false。空的CharSequence（length（）=0）将返回false。
请注意，该方法不允许使用前导符号（正号或负号）。此外，如果字符串通过了数值测试，则在按整数解析时，它仍可能生成NumberFormatException。parseInt或Long。parseLong，例如，如果值分别超出int或long的范围。
StringUtils.isNumeric(null) = false
