Java: Remove String from StringBuilder
提问by user2341387
I want to remove String from StringBuilder
我想从 StringBuilder 中删除 String
Example
例子
String aaa = "sample";
String bbb = "sample2";
String ccc = "sample3";
In another part
在另一部分
StringBuilder ddd = new StringBuilder();
ddd.append(aaa);
ddd.append(bbb);
ddd.append(ccc);
I want to check if StringBuilder ddd contains String aaa and remove it
我想检查 StringBuilder ddd 是否包含 String aaa 并将其删除
if (ddd.toString().contains(aaa)) {
//Remove String aaa from StringBuilder ddd
}
Is that possible? Or is there any other way to do like that?
那可能吗？或者有没有其他方法可以做到这一点？

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

if(start < 0)
return;
sb.delete(start, start + s.length());
}

Create a string from ddd and use replace().
从 ddd 创建一个字符串并使用 replace()。
ddd.toString().replace(aaa,"");
