1. 单行注释(Single Line Comment)格式:以双斜线(//)开头,后跟注释内容。作用:单行注释是用于在代码中添加对特定行或语句的解释和说明,它们仅在同一行起作用,对其他代码行不产生影响。【示例】java int x = 10; // 定义一个整数变量x并赋值为10 2. 多行注释(Multi-line Comment)格式:以斜杠...

实际情况中要是比较复杂的情况,可能Pattern.MULTILINE模式和Pattern.DOTAL模式需要同时指定来匹配多行,代码如下, import java.util.regex.Pattern; import java.util.regex.Matcher; public class Main { public static void main(String[] args) { Pattern p1 = Pattern.compile("^a.*b$"); ...
