title: How to convert a double array into a int array
body: <p>Hello everyone my name is Fyree, I have recently been finishing up a school assignment, and am in need of some assistance. First let me give you the second half of my code to which this question pertains:</p>
  
  <pre><code>public class Rate_Graph_Graph extends Rate_Graph1{
         double Aa, Bb, Cc, Dd, Ee, Ff;
         public void anotheractionPerformed(ActionEvent ae)
         {
            if (ae.getSource() == calc){
              Aa = Double.parseDouble(bv1.getText());
              Bb = Double.parseDouble(ev_1.getText());
              Cc = Double.parseDouble(ev_2.getText());
              Dd = Double.parseDouble(ev_3.getText());
              Ee = Double.parseDouble(ev_4.getText());
              Ff = Double.parseDouble(ev_5.getText());
            }
         }
         JLabel graphLabel;
         double[] data = {Aa, Bb, Cc, Dd, Ee, Ff};
         final int finalInt = 50;
         public void paintGraph(Graphics g){
         super.paintComponent(g);
         Graphics2D g2 = (Graphics2D)g;
  
         int w = getWidth();
         int h = getHeight();
  
         graphLabel = new JLabel ("&lt;HTML&gt;&lt;FONT SIZE =+25&gt;Line Graph showing the Return Rate&lt;/FONT&gt;");
         add(graphLabel);
  
         g2.draw(new Line2D.Double(finalInt, finalInt, finalInt, h-finalInt));
         g2.draw(new Line2D.Double(finalInt, h-finalInt, w-finalInt, h-finalInt));
         Font font1 = g2.getFont();
         FontRenderContext fontRender = g2.getFontRenderContext();
         LineMetrics lineMetrics = font1.getLineMetrics("0", fontRender);
         float ft = lineMetrics.getAscent()+lineMetrics.getDescent();
         String str = "";
  
         g.drawString("Aa", 5, 315);
         g.drawString("Bb", 5, 260);
         g.drawString("Cc",5,205);
         g.drawString("Dd",5,150);
         g.drawString("Ee",5,100);
         g.drawString("Ff",5,55);
  
         g.drawString("Beginning Value",50,335);
         g.drawString("Yeatr 1 Value",175,335);
         g.drawString("Year 2 Value",300,335);
         g.drawString("Year 3 Value",425,335);
         g.drawString("Year 4 Value",550,335);
         g.drawString("Year 5 Value",675,335);
  
         float ft2 = finalInt + ((h - 2*finalInt) - str.length()*ft)/2 + lineMetrics.getAscent();
         for(int i = 0; i &lt; str.length(); i++){
          String strLetter = String.valueOf(str.charAt(i));
          float ft3 = (float)font1.getStringBounds(strLetter, fontRender).getWidth();
          float ft4 = (finalInt - ft3)/2;
          g2.drawString(strLetter, ft3, ft4);
          ft2 += ft;
         }
         str = "YEARS";
         ft2 = h - finalInt + (finalInt - ft)/2 + lineMetrics.getAscent();
         float ft3 = (float)font1.getStringBounds(str, fontRender).getWidth();
         float ft4 = (w - ft3)/2;
         g2.drawString(str, ft4, ft2);
         double xInc = (double)(w - 2*finalInt)/(data.length-1);
         double scale = (double)(h - 2*finalInt)/getMax();
         g2.setPaint(Color.green.darker());
         for(int i = 0; i &lt; data.length-1; i++){
             double x1 = finalInt + i*xInc;
             double y1 = h - finalInt - scale*data[i];
             double x2 = finalInt + (i+1)*xInc;
             double y2 = h - finalInt - scale*data[i+1];
             g2.draw(new Line2D.Double(x1, y1, x2, y2));
          }
     }
     private double getMax()
     {
      int max = -Integer.MAX_VALUE;
      final int[] intData = new int[data.length];
      for(int i = 0; i &lt; data.length; i++){
         if(data[i] &gt; max)
          max = data[i];
      }
      return max;
     }
     public static void main(String[]args)
     {
      JFrame f = new JFrame();
      f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      f.add(new GraphingData());
      f.setSize(800,400);
      f.setLocation(200,200);
      f.setResizable(false);
      f.setVisible(true);
     }
  }
  </code></pre>
  
  <p>Now here is what my question is, how do you I convert the double[] data array that I have above into an int array so that I am able to use it in the private double getMax() method that is at the end of the code (I get the error: "incompatible types: possible lossy of conversion from double to int" when I try to do it without the conversion)? Any help is appreciated as this assignment is due later today!</p>
