### 試したこと
|
|

|
-
文字列同士を比べる際にまずはstring→charに変換し、文字列コードで比較すると思うのですが、
|
|
90
|
-
|
|
91
|
-
この手順だけで比較するとString型配列とchar型配列の違いでエラーが出てしまいます。
|
|
92
|
-
|
|
93
|
-
```
|
|
94
|
-
|
|
95
|
-
Exception in thread "main" java.lang.StringIndexOutOfBoundsException:
|
|
96
|
-
|
|
97
|
-
String index out of range: 1
|
|
98
|
-
|
|
99
|
-
```
|
|
100
|

|
|

上記手順で抜けている点のアドバイスをお願いいたします。
