Answer to Question #239024 in Java | JSP | JSF for guru

Question

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: Enter a sentence: Welcome to my NUST.

Sample run 2: Enter a sentence: The nust is a great institution of high learning.

Output: The Namibia University of Science and Technology is a great institution of high learning.
