String class Basic Methods

In this problem, you will create a program that reads a string from standard input, calls key String class methods (length(), charAt(), toUpperCase()), and displays the character count, first character, and uppercase conversion to standard output.

Learning Objective: Understand the basics of text processing using key methods of the String class (length(), charAt(), toUpperCase()) from Java's standard library

Overview

Write a program that reads a string from standard input and uses String class methods to get the length, retrieve a character at a specific position, and convert to uppercase.

Input Format

A string (e.g. hello)

Specifications

1. Read a string from standard input and store it in a variable text
2. Use length() to get the character count and print in the format "Length: X"
3. Use charAt(0) to get the first character and print in the format "First: x"
4. Use toUpperCase() to convert to uppercase and print in the format "Upper: XXX"

Output Format

Length: 5
First: h
Upper: HELLO
