you have 2 array blocks
1st array block is [0]<block[0]<number = 3
2nd array block is [1]<block[0]<number = 7
if i was to do both end numbers in each array block it would look like this
1st block is [0]<block[2]<number = 8
2nd block is [1]<block[4]<number = 4
java counts each array block and array number starting with 0 then 1
so basicly 0 is 1 strange but it makes it easier for java :)

you can imagine this as an 3×5 table.
0 and 2 select the row and column.

Henry Mauer Imagin having 2 people holding n amount of fruit in a particular order apple,pear,pineapple ect ect

Block 1 is the person your selecting
Block 2 is the fruit that person is holding
So let's say person 1 is holding 3 fruit in the particular order above
[0] = Person 1 ( array 1)
[1]= fruit index at 2 which is a pear🧑🍐 (elements) so...
[1][2] would be person 2 holding a pineapple 👧🍍
😄 hope that helps
