java正则表达式获取大括号小括号内容并判断数字

private static String regex = "\\{([^}])\\}";//匹配大括号
 private static String regexx = "\\(([^}])\\)";//匹配小括号
 public static void main(String[] args) {
 String dakuohao = "{a+b}={c+d}>{d}";
 Pattern pile = Pattern.pile(regex);
 Matcher matcher = pile.matcher(dakuohao);
 while(matcher.find()){
 String group = matcher.group();
 System.out.print(group+";");
 }
 
 System.out.println();
 
 String xiaokuohao = "(a+b)=(c+d)>(d)";
 Pattern p = Pattern.pile(regex);
 Matcher mat = p.matcher(dakuohao);
 while(mat.find()){
 String group = mat.group();
 System.out.print(group+";");
 }
