Java 中的正則表示式“z”構造
子表示式/元字元 “\z” 匹配字串的末尾。
示例 1
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class RegexExample {
public static void main( String args[] ) {
String regex = "Tutorialspoint\z";
String input = "Hi how are you welcome to Tutorialspoint";
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(input);
int count = 0;
while(m.find()) {
count++;
}
System.out.println("Number of matches: "+count);
}
}輸出
Number of matches: 1
示例 2
以下 Java 程式驗證給定的輸入文字是否以數字結尾。
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class Data {
public static void main( String args[] ) {
String regex = "[0-9]\z";
String input = "Hi how are you \n this is sample text \n this is third line 554";
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(input);
if(m.find()) {
System.out.println("Given input ends with a digit");
} else {
System.out.println("Given input doesn’t end with a digit");
}
}
}輸出
Given input ends with a digit
