Java considers the String data type as non-primitive, because it contains a sequence of characters

and hence there is a predefined class called String dedicated to String processing. The String class

has a lot of functions and continues to grow. See

https://www.tutorialspoint.com/java/java_strings.htm for more on strings. Your task is to then create

a java program that when give a sentence will replace the first occurrence of NUST with Namibia

University of Science and Technology.

Sample run 1:

--- Input ---
Welcome to my NUST

--- Expected output (text)---
Welcome to my Namibia University of Science and Technology.

Sample run 2:

--- Input ---
The nust is a great institution of high learning.

--- Expected output (text)---
The Namibia University of Science and Technology is a great institution of high learning.

Sample run 3:

--- Input ---
The NuSt was renamed from Polytechnic Of Namibia under Act No. 7 of 2015.

--- Expected output (text)---

Sample run 5:

--- Input ---
nUsT, formerly known as Polytechnic of Namibia, is an institute of tertiary education in Windhoek, Namibia

--- Expected output (text)---

Here's a code I wrote
{
public static void main(String[] args) {
Scanner in=new Scanner(System.in);
String org_str=in.nextLine();
String rep_str="Namibia University of Science and Technology";
String str=org_str.replace("NUST",rep_str);
System.out.println(str);
}
}
