今天爱分享给大家带来有一个数据文件:123 34 17 651234 345….这些数据都是随机产生的,编写程序读出该文件.并将其以从大到小的顺序输出到另一个文件中.【面试题详解】，希望能够帮助到大家。
public void readtext(){
File file = new File("D:\test.txt");
List list= new ArrayList();
try {
BufferedReader br=new BufferedReader(new FileReader(file));
String data = "";
String line = null;
while ( (line = br.readLine()) != null) {
data = data.concat(line);
}
StringTokenizer stoken = new StringTokenizer(data, " ");
while (stoken.hasMoreTokens()) {
int i = Integer.parseInt(stoken.nextToken());
list.add(i);
}
} catch(Exception ex) {}
String[] str = new String[list.size()];
for(int i=0;i=i;j--) {
if(str[j]>str[j-1]) {
iTemp = str[j-1];
str[j-1] = str[j];
str[j] = iTemp;
}
}
String result = "";
for(int i=0;i
