Java:从 StringBuilder 中删除字符串 [英] Java: Remove String from StringBuilder

问题描述

我想从 StringBuilder 中删除 String

I want to remove String from StringBuilder

示例

String aaa = "sample";
String bbb = "sample2";
String ccc = "sample3";

另一部分

StringBuilder ddd = new StringBuilder();
ddd.append(aaa);
ddd.append(bbb);
ddd.append(ccc);

我想检查 StringBuilder ddd 是否包含字符串 aaa 并删除它

I want to check if StringBuilder ddd contains String aaa and remove it

if (ddd.toString().contains(aaa)) {
    //Remove String aaa from StringBuilder ddd
}

这可能吗?或者有没有其他方法可以做到这一点?

Is that possible? Or is there any other way to do like that?

推荐答案

试试这个

    int i = ddd.indexOf(aaa);
    if (i != -1) {
        ddd.delete(i, i + aaa.length());
    }
