字元類\p{Sc}
匹配任何貨幣符號。
以下範例顯示了Unicode字元類匹配的用法。
package com.yiibai;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class UnicodeCharacterClassDemo {
private static final String REGEX = "\\p{Sc}";
private static final String INPUT = "[Bb12 \tc$!\u03B1";
public static void main(String[] args) {
// create a pattern
Pattern pattern = Pattern.compile(REGEX);
// get a matcher object
Matcher matcher = pattern.matcher(INPUT);
while(matcher.find()) {
//Prints the start index of the match.
System.out.println("Match String start(): "+matcher.start());
}
}
}
`
編譯並執行上面的程式,這將產生以下結果 -
Match String start(): 8
