Java: see the content of 2d array

this nifty snippet allows to accept and print the 2d array:

for (int i = 0; i < rowSize; i++) {
for (int j = 0; j < columnSize; j++) {
myArray[i][j] = sc.nextInt();}}

System.out.println(Arrays.deepToString(myArray));

Using the Chart.js

I need to use new chart.js to render the pie charts. However, I don’t know how to use it,

these are the steps I followed:

  1. Install node.js from installer then restart
  2. in command prompt: npm install npm -g
  3. add the canvas id to the place where you want to see the chart
    <canvas id="myChart" width="400" height="400"></canvas>
  4. add the script for the chart
    1. <script>
      var ctx = document.getElementById("myChart");
      var myChart = new Chart(ctx, {

      ……………………………..}

new Chart is the constructor for the chart.

 

Action time: Let’s start some project

Dear readers and me, I’ve decided that I should start developing my own application. Only this action can justify my accumulation of knowledge. Therefore, let’s decide on couple things:

  1. Frontend: jQuery, AJAX and JavaScript
  2. Backend: Spring framework

As for app idea, I’ve decided that I will be making clone of project which I’m working on now. But I won’t reuse any materials from it, only the knowledge I’ve acquired. I want my project to be opensource so all the codes will be available on my GitHub account. The link I will put once I got anything to show.

Thank you.
