maximum size of String Array in Java

Question

What is the maximum number of strings the String Array can hold in String Array in java? I am trying to fill a String array in java with as many as around 9000 entries and it is crashing

Thanks, Nerd

In theory? Any array can contain up to `Integer.MAX_VALUE` elements. But your memory may be limiting it. — RealSkeptic, Jan 18 '15 at 13:56
The error I get is this " java.lang.VerifyError: Rejecting class com.example.Nerd.sample_app.MainActivity2 because it failed compile-time verification (declaration of 'com.example.Nerd.sample_app.MainActivity2' appears in /data/app/com.example.Nerd.sample_app-1/base.apk)" — nerd, Jan 18 '15 at 13:58
Do you use external libraries? Maybe this post will help: http://stackoverflow.com/a/9522281/3579095 — Lars, Jan 18 '15 at 14:06

The max size of any array (Object or primitive) is bound by the max size of an int -> 2^32 - 1. Approximately 2 billion.

When you create a array you must specify the size of the array as a int. So in that case if you are having enough memory the maximum length of a array is Integer.MAX_VALUE which is equals to 2^31-1 But in real world scenarios this limit can be lot less than the actual maximum.
