私のプログラムを実行すると、ユーザーメニューの1を入力してカテゴリを検索しても項目情報のリストは表示されません。しかし、81行目でコードを修正する方法がわかりません。
マイ出力：

5 to remove old records
or enter '6' to quit.

のJava：
String INPUT_PROMPT = "\nPlease enter the number:\n" +
"1 to search category"
+ "\n2 to search dietary" + "\n3 to display all records" + "\n4 to insert record" + "\n5 to remove old records " + "\nor enter '6' to quit." +"\n";
System.out.println(INPUT_PROMPT);
try
{
BufferedReader reader = new BufferedReader
(new InputStreamReader (System.in));
line = reader.readLine();
while(!line.equals("6"))
{
switch(line)
{
//Search word for Category
case "1": <-----Line 81
int i=0;
while(i<prdct.size())
{
if(prdct.get(i).category.contains(line))
{
System.out.println(prdct.get(i));
}
i++;
}
if(i == 0)
{
System.out.println("Record not found");
}
break;
case "3":
for(int h=0; h<prdct.size(); h++)
{
System.out.println(prdct.get(h));
}
break;
}
System.out.println(INPUT_PROMPT);
line = reader.readLine();
}
}
catch(Exception e){
System.out.println("Input Error!");
}
