Now, let’s explore a straightforward example where we declare an empty array with a predefined size and then use aforloop to initialize its values. Consider the following Java code: publicclassDeclareEmptyArray{publicstaticvoidmain(String args[]){intsize=5;intarray[]=newint[size];for(inti=...
So, it is necessary to provide a value such as \0 that indicates empty or null. Here in the code, we assigned a \0 to the char to initialize it. public class SimpleTesting { public static void main(String[] args) { char ch = '\0'; // equivalent zero char value System.out....

The important point here is to mark the secure string as read-only before returning it – it is very unlikely that you’ll need to edit a secure string that was created from an existing string. You’ll also note that in the above example I used unsafe code to initialize the SecureString...
