java使用正则表达式匹配和提取字符

  1.匹配字符串

public static boolean isLegalInputLine(String line )   {

        Pattern p =Pattern.compile("GraphType\\s*=\\s*\".+\"\\s*");
     	Matcher m = p.matcher(line);
    	boolean r =m.matches(); 
    
    	return r;
    	
    }

 2.匹配并提取字符串

public List getString(String s) {

   List strs = new ArrayList();
   Pattern p = Pattern.compile("GraphType\\s*=\\s*\".+\"\\s*");
   Matcher m = p.matcher(s);
   while(m.find()) {
     strs.add(m.group());

   }
   return strs;
}
