我是设置了一个Button button_char按钮,点击按钮之后的操作 |
|
![]() |
想要代码,自己也知道用io,可是不太会呀!姓名和号码用空格区分
|
![]() 60分 |
用list吧,数组你提前知道多大吗?不然会越界的!
FileReader fr = null;
BufferedReader br = null;
List<String> nameList = new ArrayList<String>();
List<String> phoneList = new ArrayList<String>();
try {
fr = new FileReader(new File("H:\test.txt"));
br = new BufferedReader(fr);
String line = null;
String[] strs = null;
while ((line = br.readLine()) != null) {
strs = line.split("\s+");
nameList.add(strs[0]);
phoneList.add(strs[1]);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (br != null) {
try {
br.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if (fr != null) {
try {
fr.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
