I’m working on a java project where I need to find and replace a specific substring within each string in a string array. Here’s a simplified version of my code:

public class StringArrayReplace{
     public static void main(String[] args){
         String[] stringArray = {"apple","banana","apricot","grape"};
         String tofind = "ap";
         String toreplace = "AP";
         
        
     }
} 

I’m looking to replace every occurrence of the substring ‘tofind’ with ‘toreplace’ in each element of the ‘stringArray’. For example, the above array should transform into ‘{“APple”,”banana,”APricot”,”grape”}’.

What would be an efficient way to achieve this in java? Are there any built-in methods or best practices I should follow to ensure the code is optimal and readable?
