java.lang.Character.getDirectionality(int codePoint) 返回給定字元(Unicode程式碼點)的Unicode方向屬性。字元指向來計算文字的視覺順序。未定義字元的指向值為 DIRECTIONALITY_UNDEFINED。
以下是java.lang.Character.getDirectionality()方法的宣告
public static byte getDirectionality(int codePoint)
codePoint - 該字元(Unicode程式碼點)屬性指向要求
此方法返回字元的方向屬性。
NA
下面的例子顯示了lang.Character.getDirectionality()方法的使用。
package com.yiibai; import java.lang.*; public class CharacterDemo { public static void main(String[] args) { // create 2 int primitives cp1, cp2 int cp1, cp2; // assign values to cp1, cp2 cp1 = 0x2323; cp2 = 0x2c60; // create 2 byte primitives b1, b2 byte b1, b2; // assign directionality of cp1, cp2 to b1, b2 b1 = Character.getDirectionality(cp1); b2 = Character.getDirectionality(cp2); /** * byte value 13 represents DIRECTIONALITY_OTHER_NEUTRALS * byte value -1 represents DIRECTIONALITY_UNDEFINED */ String str1 = "Directionality of cp1 is " + b1; String str2 = "Directionality of cp2 is " + b2; // print b1, b2 values System.out.println( str1 ); System.out.println( str2 ); } }
讓我們來編譯和執行上面的程式,這將產生以下結果:
Directionality of cp1 is 13 Directionality of cp2 is -1
