我想做一个函数,它获取一个字符串,如果它有内联注释,它删除它。我知道这听起来很简单,但我想确保im这样做正确,例如:
I'd like to do a function which gets a string and in case it has inline comments it removes it. I know it sounds pretty simple but i wanna make sure im doing this right, for example:
private String filterString(String code) { // lets say code = "some code //comment inside" // return the string "some code" (without the comment) }我想了两种方法:随时咨询其他意见
I thought about 2 ways: feel free to advice otherwise
可以告诉我什么是最好的方法,并告诉我应该怎么做? (请不要建议太先进的解决方案)
can u tell me what's the best way and show me how it should be done? (please don't advice too advanced solutions)
编辑:可以用扫描仪对象做某些事情吗? (im using this object anyway)

推荐答案要使用正则表达式替换找到常量子字符串之前的子字符串有点多。
To find the substring before a constant substring using a regular expression replacement is a bit much.
您可以使用 indexOf()来检查注释开始的位置和 substring()获取第一部分,如:
You can do it using indexOf() to check for the position of the comment start and substring() to get the first part, something like:
String code = "some code // comment"; int offset = code.indexOf("//"); if (-1 != offset) { code = code.substring(0, offset); }更多推荐
