獲得輸入字符串長度超過60

Question

我正在寫一個程序計算給定序列中氨基酸代碼的概率。當我嘗試從用戶的輸入，它顯示了以下錯誤

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 407 
    at java.lang.String.charAt(String.java:646) 
    at BNC.Sequence.<init>(Sequence.java:50) 
    at BNC.Navie_Bayesian_Classifier.main(Navie_Bayesian_Classifier.java:34) 
407Java Result: 1 

我的代碼是

 try(Scanner scan=new Scanner(new File("F:\\Thiyaga\\ProteinSequence\\Test.txt"))) 
    { 


    line = scan.nextLine().trim(); 
    length=line.length(); 
// line=reader.readLine(); 
    } 
      System.out.print(length); 
    for(i=0;i<20;i++) 
    { 
     count[i]=0; 
     probility[i]='\0'; 
    } 
      for(int k=0;k<length;k++) 
    { 
     switch(line.charAt(k)) 
        { 

它顯示了在開關或長度誤差在

我輸入的這種形式

所呈現的代碼的執行不會導致錯誤。這裏是給定的代碼片段的簡化版本，與給定的輸入文件工作得非常好：

import java.util.Scanner; 
import java.io.File; 
import java.io.IOException; 

public class XXX{ 

    public static void main(String[] args){ 
    try(Scanner scan=new Scanner(new File("Test.txt"))){ 
     String line = scan.nextLine().trim(); 
     int length=line.length(); 
     for(int k=0;k<length;k++) 
     System.out.println(k + " " + line.charAt(k)); 
    } catch (IOException e){ 
     e.printStackTrace(); 
    } 
    } 
}
