java.lang.Character.isSupplementaryCodePoint(int codePoint)%uA0确定指定字符(Unicode代码点)是否在补充字符范围。
声明
以下是java.lang.Character.isSupplementaryCodePoint()方法的声明
public static boolean isSupplementaryCodePoint(int codePoint)
参数
-
codePoint%uA0- 进行测试的字符(Unicode代码点)
返回值
如果指定的代码点是在MIN_SUPPLEMENTARY_CODE_POINT和MAX_CODE_POINT(含)之间此方法返回true，否则返回false。
异常
-
NA
例子
下面的例子显示lang.Character.isSupplementaryCodePoint()方法的使用。
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 = 0x10ffd cp2 = 0x004ca // create 2 boolean primitives b1, b2 boolean b1, b2 /** * check if cp1, cp2 are in supplementary character range * and assign results to b1, b2 */ b1 = Character.isSupplementaryCodePoint(cp1) b2 = Character.isSupplementaryCodePoint(cp2) String str1 = "cp1 represents a supplementary code point is " + b1 String str2 = "cp2 represents a supplementary code point 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 represents a supplementary code point is true cp2 represents a supplementary code point is false
