boolean matches(String regex):判断该字符串是否匹配指定的正则表达式; String replaceFirst(String regex, String replaceStr):将该字符串中第一个匹配regex的子串替换成replaceStr; String replaceAll(String regex, String replaceStr):将该字符串中所有匹配regex的子串替换成replaceStr; String[] split(String regex)...
String[] split(CharSequence input, int limit) 功能和String[] split(CharSequence input)相同,增加参数limit目的在于要指定分割的段数 Stringregex ="\\?|\\*";Patternpattern =Pattern.compile(regex);String[] splitStrs = pattern.split("123?123*456*456");//123 123 456 456String[] splitStrs2 =...

,并输出“Match found!” 需要注意的是,如果正则表达式本身包含“^”或“$”,则不需要在字符串的开头和结尾分别使用“^”和“$”。例如: 代码语言:java 复制 String str = "Hello World!"; String regex = "Hello.*World.*"; if (str.matches(regex)) { System.out.println("Match found!");...

正则表达式用于Java的String.matches方法,可以使用“^”和“$”匹配字符串的开头和结尾,或者使用“.*”匹配任意字符。例如: 代码语言:java 复制 Stringstr="Hello World!";Stringregex="Hello.*World!";if(str.matches(regex)){System.out.println("Match found!");}else{System.out.println("No match fo...
