java.lang.Character.isIdentifierIgnorable(int codePoint)%uA0确定指定字符(Unicode代码点)应被视为一个可忽略的字符在Java标识符或Unicode标识符。
下面Unicode字符都忽略了Java标识符或Unicode标识符：
-
不是空白的ISO控制字符
-
&aposu0000&apos %uA0通过%uA0&aposu0008&apos
-
&aposu000E&apos %uA0通过%uA0&aposu001B&apos
-
&aposu007F&apos %uA0通过%uA0 &aposu009F&apos
-
-
具有格式FORMAT普通类值的所有字符
声明
以下是java.lang.Character.isIdentifierIgnorable()方法的声明
public static boolean isIdentifierIgnorable(int codePoint)
参数
-
codePoint%uA0- the character (Unicode code point) to be tested
返回值
This method returns true if the character is an ignorable control character that may be part of a Java or Unicode identifier, false otherwise.

例子
The following example shows the usage of lang.Character.isIdentifierIgnorable() method.
package com.yiibai import java.lang.* public class CharacterDemo { public static void main(String[] args) { // create 2 int primitives cp1, cp2 int cp1, cp2 // assign values to cp1, cp2 cp1 = 0x008f cp2 = 0x0abc // create 2 boolean primitives b1, b2 boolean b1, b2 // assign isIdentifierIgnorable results of cp1, cp2 to b1, b2 b1 = Character.isIdentifierIgnorable(cp1) b2 = Character.isIdentifierIgnorable(cp2) String str1 = "cp1 is an ignorable control character is "+b1 String str2 = "cp2 is an ignorable control character is "+b2 // print b1, b2 values System.out.println( str1 ) System.out.println( str2 ) } }
让我们来编译和运行上面的程序，这将产生以下结果：
cp1 is an ignorable control character is true cp2 is an ignorable control character is false
