java删除字符串中的具体字符 例如“abcdecdabac” 删除“ac” 结果应该是“bdedb” Java 字符串解析，任意组合。

我也是新手，只会这种删2遍的：
String b = "abcdecdabac";
b=b.replace("a",""); //第一次删除后字符串b应该是"bcdecdbc"
b=b.replace("c",""); //在第一次的结果上第二次删除后就是"bdedb"了
求大神有简单的方法。。。
你如果想替换掉a和c的话用两次String.replace('a','').replace('c','')
你如果想替换掉ac就用String.replace('ac','');
public static void main(String[] args) {
String s = "abcdecdabac";
String reg = "[a,c]";
s = s.replaceAll(reg, "");
System.out.println(s);
}
围观的，其实我写的也不是挺好，抛砖啊
