这是我的输出：“四分和七年前......”
然而，预期的输入是：“四分和七年前……”（引号和‘四’之间有一个空格”。
如何保留前导空格？到目前为止，这是我的代码。
public void checkDocument(Reader in, InputStream input, Writer out) throws IOException {
Scanner sc = new Scanner(input);
TokenScanner tok=new TokenScanner(in);
Token too;
Set<String> fileCor=new HashSet<String>();
while (tok.hasNext()){
too=tok.next();
System.out.println(too);
if (too.isWord()){
if (!(dict.isWord(too.toString()))){
int n=1;
fileCor=corr.getCorrections(too.toString());
List<String> sortedOptions=new LinkedList<String>(fileCor);
Collections.sort(sortedOptions);
System.out.println("The word: "+too.toString()+" is not in the dictionary. Please enter the number corresponding with the appropriate action:");
System.out.println("0: Ignore and continue");
System.out.println("1: Replace with another word");
for (int i=0;i<sortedOptions.size();i++){
n=n+i+1;
System.out.println((i+2)+": Replace with \""+sortedOptions.get(i)+"\"");
}
int choice=getNextInt(0, n, sc);
if (choice==0){
}
else if (choice==1){
out.write(getNextString(sc).trim());
}
else out.write(sortedOptions.get(choice-2).trim());
}
else out.write(too.toString().trim());
}
else {
out.write(too.toString());
}
}
System.out.println("Document completed");
}
}
