Java Character.isSupplementaryCodePoint()用法及代码示例

java.lang.Character.isSupplementaryCodePoint(int codePoint)是java中的内置方法，用于确定指定字符(Unicode代码点)是否在补充字符范围内。

用法:

public static boolean isSupplementaryCodePoint(int codePoint)

参数：整数类型的codePoint是指要测试的字符(Unicode代码点)。

返回值：如果指定的代码点在MIN_SUPPLEMENTARY_CODE_POINT和MAX_CODE_POINT(含)之间，则此方法返回true，否则返回false。

以下示例程序旨在说明Character.isSupplementaryCodePoint()方法：

示例1:

// Code to illustrate the isSupplementaryCodePoint() method 
import java.lang.*; 
  
public class gfg { 
  
    public static void main(String[] args) 
    { 
  
        // Create 2 int primitives c1, c2 and assign values 
        int c1 = 0x10ffd, c2 = 0x154ca; 
  
        boolean bool1 = Character.isSupplementaryCodePoint(c1); 
        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; 
  
        // Displaying the result 
        System.out.println(str1); 
        System.out.println(str2); 
    } 
}

输出：

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

示例2:

// Code to illustrate the isSupplementaryCodePoint() method 
import java.lang.*; 
  
public class gfg { 
  
    public static void main(String[] args) 
    { 
  
        // Creates 2 int primitives c1, c2 and assign values 
        int c1 = 0x45ffd, c2 = 0x004ca; 
  
        boolean bool1 = Character.isSupplementaryCodePoint(c1); 
        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; 
         
        // Displaying the result 
        System.out.println(str1); 
        System.out.println(str2); 
    } 
}

输出：

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