Question

 System.out.println("Here is the list by Category Type.");
 System.out.println("Please enter the category you are looking"
                  + " for.");
 String search = user_input.next();
 System.out.println("Here is what we found for that category: ");

 for (int row = 0; row < store.length; row++) {
    for (int column = 0; column < store[row].length; column++)
       if (store[row][column].toUpperCase().contains(search.toUpperCase()))
          System.out.println(String.format("%20s\t",store[row][column]));

这是我的代码，用于打印数组中的某些行，但我得到的输出是我不想要的，我不知道如何去做。对于陈述

的部分的示例

"Please enter the category you are looking for."

然后我输入：学校用品，它有6个属于该类别的元素，输出打印出来就像这样。

以下是我们在该类别中找到的内容：

 School Supplies    
 School Supplies    
 School Supplies    
 School Supplies    
 School Supplies    
 School Supplies

我想要显示项目，而不仅仅是类别。

这是我正在查看的数组。

 String[][] store = {       
        {"Alumni Drink ware", "Gifts", "$25.00"},
        {"Binders", "School Supplies", "$3.00"},
        {"Book bag", "School Supplies", "$20.00"},
        {"Fabulous Desserts", "Textbooks", "$25.00"},
        {"Folders", "School Supplies", "$1.00"},
        {"Gift Cards", "Gifts", "$25.00"},
        {"Highlighters", "School Supplies", "$2.00"},
        {"Jacket", "Campus Gear", "$65.00"},
        {"JAVA Programming", "Textbooks", "$150.00"},
        {"Network Solutions", "Textbooks", "$75.00"},
        {"Pencils", "School Supplies", "$1.00"},
        {"Pens", "School Supplies", "$2.00"},
        {"Shorts", "Campus Gear", "$10.00"},
        {"Sweatshirts", "Campus Gear", "$40.00"},
        {"T-shirts", "campus Gear", "$15.00"},
        {"Web Design Ideas", "Textbooks", "$55.00"}};

System.out.println("Here is the list by Category Type.");
System.out.println("Please enter the category you are looking"
              + " for.");
String search = user_input.next();
System.out.println("Here is what we found for that category: ");

for (int row = 0; row < store.length; row++) {
   for (int column = 0; column < store[row].length; column++)
   if (store[row][column].toUpperCase().contains(search.toUpperCase()))
      System.out.println(String.format("%20s\t", java.util.Arrays.toString(store[row])));

我需要帮助来打印此数组中的元素吗？
