Problems in Java array subscript __java

Problem with Java array subscript out of bounds:

These problems have been occurring recently: array subscript out of bounds

there are many reasons why this type of problem occurs in line 15th. To sum up what I understand, the length of an array determines the amount of data it can load. and the
array count is zero-based,
for example: When Srring arr[]==new string[6], you can enter only six if you want to enter a name. More is the subscript out of bounds.
In addition, the array is generally used in conjunction with the For loop, so use the time to pay attention to its cyclic conditions.
