JAVA | 38 - 正则表达式 | Pattern 类 与 Matcher 类

拆分

import java.util.Arrays;
import java.util.regex.Pattern;

public class Main {
public static void main(String[] args) {
String str = "hudr34bjd393493n2432bbj34424j343";
String regex = "\\d+";
Pattern pattern = Pattern.compile(regex); // 编译正则
String strs [] = pattern.split(str); // 拆分
System.out.println(Arrays.toString(strs));
}
}

匹配

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Main {
public static void main(String[] args) {
String str = "456789876545678";
String regex = "\\d+";
Pattern pattern = Pattern.compile(regex); // 编译正则
Matcher matcher = pattern.matcher(str);
System.out.println(matcher.matches());
}
