Finding the size of a char array in Java

You can use b.length to find out how many characters there are.

This is only the number of characters, not indexing, so if you iterate over it with a for loop, remember to write it like this:

for(int i=0;i < b.length; i++)

Note the < (not a <=). It’s also important to note that since the array isn’t a class, .length isn’t a function, so you shouldn’t have parenthesis afterward.
