性格Java中的isSupplementaryCodePoint（）方法-yiteyi-C++库

这个 JAVA朗，性格。isSupplementaryCodePoint（int代码点） 是java中的内置方法，用于确定指定的字符（Unicode代码点）是否在补充字符范围内。

null

语法：

public static boolean isSupplementaryCodePoint(int codePoint)

参数： 这个 代码点 整型字符是指要测试的字符（Unicode代码点）。

返回值： 如果指定的代码点介于最小值和最大值之间，则此方法返回true，否则返回false。

下面的程序说明了这个角色。isSupplementaryCodePoint（）方法：

项目1：

                     // Code to illustrate the isSupplementaryCodePoint() method

                                         boolean                               bool2 = Character.isSupplementaryCodePoint(c2);                   
                             
                                         String str1 =                               "c1 represents a supplementary code point is "                               + bool1;                   
                                         String str2 =                               "c2 represents a supplementary code point is "                               + bool2;

                                         System.out.println(str1);

输出：

c1 represents a supplementary code point is true
c2 represents a supplementary code point is false
