For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Arrays - setup, fill, pass, process, length
this example from a Well House Consultants training course
More on this [link]

This example is described in the following article(s):
   • Java Programming Fundamentals - [link]

Source code: Irene.java Module: J050
public class Irene {

/*
Java uses true arrays - variables that contain multiple values
in successive memory locations all of which occupy the same
number of bytes. Which means that you can't extend an array
in length once you have it set.

However, Java is NOT a statically compiled language where you have
to decide how big an array is when you write / build your program -
it can decide how much memory to allocate as the program runs, and
also set up new arrays during the run - even setting up longer
arrays than were set up initially and moving content to the new
and longer area (this is NOT shown in this example)
*/


public static void main(String [] args) {
        int [] wc = spew(args); // Passing arrays
        int longest = 0, longposn = 0;
        for (int i=0; i<wc.length; i++) { // Process an array
                System.out.print(wc[i]);
                System.out.print(" ");
                if (longest < wc[i]) {
                        longest = wc[i];
                        longposn = i;
                        }
                }
        System.out.println(); // Add newline at very end
        System.out.print("Longest word - ");
        System.out.print(longest);
        System.out.println(" characters");
        System.out.print("Longest word was ");
        System.out.println(args[longposn]);
}

private static int [] spew(String [] words) {
        int n = words.length;
        int [] result = new int[n]; // Setting up new array
        System.out.print("Word count ");
        System.out.println(n);
        for (int i=0; i<words.length; i++) { // Fill an array
                result[i] = words[i].length();
                }
        return result;
        }
