如何在 Java 中查找给定字符的 unicode 类别?

Character 类是 Object 的子类，它将原始类型 char 的值包装在对象中。Character 类型的对象包含一个类型为 char 的字段。我们可以使用 getType() 方法确定特定字符的 unicode 类别。它是 Character 类的静态方法，它返回一个表示 unicode 一般类别的 char ch 的 整数 值。
语法
public static int getType(char ch)
示例
public class CharacterTypeTest {
public static void main(String args[]) {
System.out.println("T represnts unicode category of: " + Character.getType('T'));
System.out.println("@ represnts unicode category of: " + Character.getType('@'));
System.out.println(") represnts unicode category of: " + Character.getType(')'));
System.out.println("1 represnts unicode category of: " + Character.getType('1'));
System.out.println("- represnts unicode category of: " + Character.getType('-'));
System.out.println("_ represnts unicode category of: " + Character.getType('_'));
System.out.println("a represnts unicode category of: " + Character.getType('a'));
}
}
输出
T represnts unicode category of: 1 @ represnts unicode category of: 24 ) represnts unicode category of: 22 1 represnts unicode category of: 9 - represnts unicode category of: 20 _ represnts unicode category of: 23 a represnts unicode category of: 2
