Java 中的 character . issuplementarycode point()方法
原文:https://www . geesforgeks . org/character-issuplementarycode point-method-in-Java/
java . lang . character . issuplementAryCodePoint(int CodePoint)是 Java 中的一个内置方法，用于确定指定的字符(Unicode 代码点)是否在补充字符范围内。
语法:
public static boolean isSupplementaryCodePoint(int codePoint)
参数:整数型的码点是指需要测试的字符(Unicode 码点)。
返回值:如果指定的码点在 MIN _ sublimited _ CODE _ POINT 和 MAX_CODE_POINT(含)之间，则该方法返回 true，否则返回 false。
下面的程序说明了 character . issuplementarycode point()方法:
程序 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
程序二:
// 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
