在此,我将单词存储在一个数组列表中,并将与其对应的相应电话号码存储在另一个数组列表中。我希望能够输入一个数字并返回另一个列表中对应的所有单词。我有这样的数组列表设置。
List<String> listWords = new ArrayList<String>(); // An ArrayList which stores all added words.
List<String> listNum = new ArrayList<String>();// An ArrayList which stores all phone numbers that correspond to all the added words
单词的转换就像在电话键盘上一样(即 2 = a,b,c 3 = d,e,f 等)。
我也像这样简单地添加单词;
public void readWords()
{
PhoneWords ph = new PhoneWords();
try
{
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("words.txt");
BufferedReader br = new BufferedReader(new InputStreamReader(fstream));
String strLine;
//Read File Line By Line
while ((strLine = br.readLine()) != null)
{
String phNum = ph.word2Num(strLine);
listWords.add(position, strLine);
listNum.add(position, phNum);
position++; // index position, only used when initally adding the words
}
}catch (Exception e)
{
//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
