- Character.getType(char ch)是Java中的一种内置方法,它返回一个指示字符的常规类别的值。此方法不能处理补充字符。要支持所有Unicode字符(包括补充字符),请使用getType(int)方法。
用法:
public static int getType(char ch)
参数:该方法接受字符数据类型的一个参数ch,该参数ch是要测试的字符。
返回值:此方法返回一个整数类型的值,表示字符的常规类别。
以下示例程序旨在说明Character.getType(char ch)方法的使用:
示例1:import java.lang.*; public class gfg { public static void main(String[] args) { // Create 2 character primitives ch1, ch2 and assigning values char c1 = 'K', c2 = '%'; // Assign getType values of c1, c2 to int primitives int1, int2 int int1 = Character.getType(c1); int int2 = Character.getType(c2); String str1 = "Category of " + c1 + " is " + int1; String str2 = "Category of " + c2 + " is " + int2; System.out.println( str1 ); System.out.println( str2 ); } }
输出:Category of K is 1 Category of % is 24
示例2:
import java.lang.*; public class gfg { public static void main(String[] args) { // Create 2 character primitives ch1, ch2 and assigning values char c1 = 'T', c2 = '^'; // Assign getType values of c1, c2 to inyt primitives int1, int2 int int1 = Character.getType(c1); int int2 = Character.getType(c2); String str1 = "Category of " + c1 + " is " + int1; String str2 = "Category of " + c2 + " is " + int2; System.out.println(str1); System.out.println(str2); } }
输出:Category of T is 1 Category of ^ is 27
- java.lang.Character getType(int codePoint)在所有方面都类似于先前的方法,该方法可以处理补充字符。
用法:
public static int getType(int codePoint)
参数:该方法接受整数数据类型的单个参数codePoint,表示要测试的字符(Unicode代码点)。
返回值:此方法返回一个int类型的值,表示字符的常规类别。
下面的程序演示了上述方法:
示例1:// Java program to demonstrate // the above method import java.lang.*; public class gfg { public static void main(String[] args) { // int primitives c1, c2 int c1 = 0x0037, c2 = 0x016f; // Assign getType values of c1, c2 to int primitives int1, int2 int int1 = Character.getType(c1); int int2 = Character.getType(c2); // Print int1, int2 values System.out.println( "Category of c1 is " + int1); System.out.println( "Category of c1 is " + int2); } }
输出:Category of c1 is 9 Category of c1 is 2
示例2:
// Java program to demonstrate // the above method import java.lang.*; public class gfg { public static void main(String[] args) { // int primitives c1, c2 int c1 = 0x0135, c2 = 0x015f; // Assign getType values of c1, c2 to int primitives int1, int2 int int1 = Character.getType(c1); int int2 = Character.getType(c2); // Print int1, int2 values System.out.println( "Category of c1 is " + int1); System.out.println( "Category of c1 is " + int2); } }
输出:Category of c1 is 2 Category of c1 is 2
