What is the maximum size of string array in Java?
2,147,483,647
It generally depends on the JVM that we’re using and the platform. Since the index of the array is int, the approximate index value can be 2^31 – 1. Based on this approximation, we can say that the array can theoretically hold 2,147,483,647 elements.

What is the size of array?
To determine the size of your array in bytes, you can use the sizeof operator: int a[17]; size_t n = sizeof(a); On my computer, ints are 4 bytes long, so n is 68. To determine the number of elements in the array, we can divide the total size of the array by the size of the array element.
What is string array in Java?
