我正在尝试编写一个代码来读取文件中的句子并计算重复的字母并将其作为字符串存储在另一个文件中作为输出。
问题是代码只计算一个重复的字母，而不会存储其他字母......

，输入文件为：
اهلاوسهلاااابكمم!!
يااهلااااومرحببااا
كككيفكم???
هههههههههههههه
我得到的输出是：
3,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ，0,0,0,0,0,0,0,0。
0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ，0,0,0,0,0,0,0,0。
0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ，0,0,0,0,0,2,0,0。
0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ，0,13,0,0,0,0,0,0。
它应该在哪里：
3,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 ，0,0,0,0,1,0,0,0。
5,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ，0,0,0,0,0,0,0,0。
0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ，0,0,0,0,0,2,0,0。
0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ，0,13,0,0,0,0,0,0。
我怎么能解决这个问题？
答案 0 :(得分：1)
看起来你让它变得复杂了。我删除了所有不必要的代码，并使用2个列表编写了一个干净的解决方案。
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
public class Repeat {
public static String text;
static String vector = "";
public static void main(String[] args) throws IOException {
String line = "اهلا وسهلاااا بكمم!!";
List<String> vals = new ArrayList<>();
vals.add("ا");
vals.add("ب");
vals.add("ت");
vals.add("ث");
vals.add("ج");
vals.add("ح");
vals.add("خ");
vals.add("د");
vals.add("ذ");
vals.add("ر");
vals.add("ز");
vals.add("س");
vals.add("ش");
vals.add("ص");
vals.add("ض");
vals.add("ط");
vals.add("ظ");
vals.add("ع");
vals.add("غ");
vals.add("ف");
vals.add("ق");
vals.add("ك");
vals.add("ل");
vals.add("م");
vals.add("ن");
vals.add("ه");
vals.add("و");
vals.add("ي");
vals.add("!");
vals.add("?");
vals.add(".");
vals.add(",");
List<Integer> results = new ArrayList<>(vals.size());
for (int i = 0; i < vals.size(); i++) {
results.add(0);
}
for (int i = 0; i < line.length(); i++) {
String s = "" + line.charAt(i);
for (int j = 0; j < vals.size(); j++) {
if (i < line.length() - 1) {
if (vals.get(j).equals(s) && vals.get(j).equalsIgnoreCase("" + line.charAt(i + 1))) {
results.set(j, results.get(j) + 1);
}
}
}
}
System.out.println(results);
}
}
这给了我输出
[3, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0]
