我有这个课程，我从文件中读取数据，程序添加了单词，并计算了每个单词，例如： （WData {word =成功，count = 1} WData {word =自动机，count = 1} Data {word = theory，count = 2}）如何排序输出并以字符A到Z开头，我是指单词and。这是我的代码 Sa类
class SA:
public class SA<T> {
int head;
int size;
T[] nodes;
public SA(int maxsize) {
head = 0;
nodes = (T[]) new Object[maxsize];
size = 0;
}
public int size() {
return size;}
public boolean empty() {
return size == 0;
public void insert(T e) {
nodes[size] = e;
size++;
}
public T find(T s) {
if (size != 0) {
for (int i = 0; i < size; i++) {
if (nodes[i].equals(s)) {
return nodes[i];
}
}
}
return null;
}
public void display() {
for (int i = 0; i < size; i++) {
System.out.println(nodes[i].toString());
}}}
这里是TextAnalyzer类：
Public class TextAnalyzer<T> {
private static class WData {
@Override
public int hashCode() {
int hash = 7;
hash = 71 * hash + Objects.hashCode(this.word);
return hash;
}
@Override
public boolean equals(Object obj) {
if (this == obj) {
return true;
}
if (obj == null) {
return false;
}
if (getClass() != obj.getClass()) {
return false;
}
final WData other = (WData) obj;
if (!Objects.equals(this.word, other.word)) {
return false;
}
return true;
}
String word;
int count;
public WData(String w, int f) {
word = w;
count = f;
}
@Override
public String toString() {
return "WData{" + "word=" + word + ", count=" + count + '}';
}
} SA<WData>list;
public TextAnalyzer() {
list=new SA<WData>(11000);
}
public void processText(String filename) {
long count = 0;
try {
Scanner sc = new Scanner(new File(filename));;
while (sc.hasNext()) {
String line = sc.next();
String st = line.replaceAll("[^a-zA-Z ]", "").toLowerCase();
processWord(st);}
list.display();
} catch (FileNotFoundException ex) {
System.out.println("There are error in processText");
}
}
public void processWord(String word) {
WData w = new WData(word, 1);
WData s = list.find(w);
if (s == null) {
list.insert(w);
} else {
s.count = s.count + 1;
}}}
