How to count the number of sub string from a split in java

Question

I have this piece of code in my java class

mystring  = mysuperstring.split("/");

I want to know how many sub-string is created from the split.

In normal situation, if i want to access the first sub-string i just write

mystring[0];

Also, i want to know if mystring[5] exist or not.

Answer 1

I want to know how many sub-string is created from the split.

Since mystring is an array, you can simply use mystring.length to get the number of substrings.

Also, i want to know if mystring[5] exist or not.

To do this:

if (mystring.length >= 6) { ... }

Answer 2

mystring  = mysuperstring.split("/");
int size = mystring.length;

remember that arrays are zero indexed, so where length = 5, the last element will be indexed with 4.

Answer 3

It's a simple way to count the sub-strings

word.split('/').length;

You can see an example of this implementation here.
