eclipse question:if you can give a few explanations while coding in java that would be great thanks!

Just so you won't have to type such a long paragraph, copy and paste below..(you may have to minipulate the paragraph to match the example...

Java is a general-purpose computer-programming language that is concurrent, class-based, object-oriented,and specifically designed to have as few implementation dependencies as possible.It is intended to let application developers "write once, run anywhere" (WORA),meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of computer architecture. As of 2016, Java is one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since been acquired by Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them. [Wikipedia].

Write a Java program that reads a given text file, outputs the text as is, and also prints the number of lines and the number of times each letter appears in the text. An uppercase letter and a lowercase letter are treated as being the same. See sample input / output below 1. 2. Requirements Make sure to include your name and Jag# as a comment . Name your class TextProcessing. Name your input file "textin.txt" . Do not use global variables; variables should be declared within methods . Main method should function as the driver .Program should read one line at a time and count the occurrence of characters within a given line (e.g. nextLine) Must be include the following methods as defined below. . public static void initializeLetterList(int[] letterCntList) l/ initializes the components of the array letterCntList to zero o public static void updateCntList(String line, intl] letterCntList) // counts the number of characters in the string line and updates the // array letterCntList o public static void writeTotals(int lineCnt, int[] letterCntList, PrintWriter out) /l outputs the value of the variable lineCnt and contents of the array // letterCntList to the output file referenced by the variable out. See sample // input / output for format. Test your program using a small test case
