使用Java正则表达式提取字符串末尾的数字一例

String reg = "\\D+(\\d+)$";    //提取字符串末尾的数字：封妖塔守卫71 == >> 71  
String s = monster.getMonsterName();  
Pattern p2 = Pattern.compile(reg);  
Matcher m2 = p2.matcher(s);  
int historyHighestLevel = 1;
if(m2.find()){  
    historyHighestLevel = Integer.parseInt(m2.group(1));
    System.out.println(m2.group(1));  // 组提取字符串  
}
