Why string of arrays in java read n-1 values??

Question

For example:
String a[]=new String[5];
for(i=0;i<a.length();i++)

Read or print only four values why but its size is 5??
But in integer type it read and print 5 values as usual....

Answer 1

Array indexing starts from 0.
So if there are 5 elements then the indexes are from 0 to 4. This means if your n=5 then the index will range from 0 to n-1.

arr.length -> returns length of the array
arr.length() -> returns length of the string
