I need help about array in java

Question

You need to arrange the product by category using 2 dimensional array. Every row must have the same category.

Can product: Corned Beef, Condensed Milk, Tuna, Evap Milk, Sprite, Beef Loaf, Coke Zero, Kremdensada, Pepsi

The expected output:
Row 1: Corned Beef, Tuna, Beef Loaf
Row 2; Condensed Milk, Evap Milk, Kremdensada
Row 3: Sprite,Coke Zero, Pepsi

Can anyone help me I don't know how to sort a string array.

Answer 1

Question is unclear and missing detail.
Assuming that they have a property "category" I would suggest first sorting them into a dictionary (key=category, value=list of products) and then creating 2d-array from that.
Doesn't look like you have to sort anything, rather just bin/group by category
