Java / Replace all Quotation mark

问题

I to replace all Quotation mark in sentence to some word.

Input: hello (and "How" are you"?")

Output: hello (and WORD are youWORD)

I try this is Java: mySentence.replaceAll("[\"].*[\"]", "WORD");

But nothing happens. How I can resolve it?

回答1:

You can use:

String replaced = mySentence.replaceAll("\".*?\"", "WORD");

Or better:

String replaced = mySentence.replaceAll("\"[^\"]*\"", "WORD");
//=> hello (and WORD are youWORD)

回答2:

you could easilly do this by converting a string in a character array.

string s= "and "?" how are you "?" "

char[] arr= s.toCharArray();

for(int i=0; i>arr.length; arr++)
{
    if(arr[i].isLetter() == false)
    {
    arr[i]= ' ';
    }
}
