Summing of double values

Question

Hello everybody, i have a problem summing double values got from JFormattedTextFields, i need to make it somehow shorter, i couldn't find such function as Math.sum or something like that, with bold i selected problematic area - if i had somewhere 100 formattedtextfields it would be a serious problem! Thanks!
package Array;
import java.text.NumberFormat;
import javax.swing.JFormattedTextField;
+public class Array extends javax.swing.JFrame {+
JFormattedTextField[] tekstalauks;
NumberFormat JFTFformats;
NumberFormat SummaFormats;
double[] vertibas;
int vDaudzums=10;
int daudzums=10;
int y=-15;
+/** Creates new form Array */+
+public Array() {+
Formats();
initComponents();
+}+
+public void PirmaDala(){+
+tekstalauks=new JFormattedTextField[daudzums];+
+double[] vertibas=new double[vDaudzums];+
for(int a=0; a<tekstalauks.length; a+){+
y=y25;+
+vertibas[a]=0;+
+tekstalauks[a]=new JFormattedTextField(JFTFformats);+
+tekstalauks[a].setValue(new Double(vertibas[a]));+
+tekstalauks[a].setBounds(10, y, 40,20);+
+jPanel1.add(tekstalauks[a]);+
+}+
+}+
+public void Formats(){+
JFTFformats=NumberFormat.getNumberInstance();
SummaFormats=NumberFormat.getNumberInstance();
+}+
+private double Summa(double vertibas[]){+*
double atbilde=0;*
atbilde=((Number)tekstalauks[0].getValue()).doubleValue()((Number)tekstalauks[1].getValue()).doubleValue();+*
return atbilde....;*
+}+
+private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {+                                        
+// TODO add your handling code here:+
double sum=Summa(vertibas);
Summa.setValue(new Double(sum));

Hi, problem is - i have for example 100 JFormattedTextFields generated on JPanel (this is already working)
I have one field where result is showing named Summa. Result is sum of each jformattedfield (total count 100) value - in bold this is example of just two first fields, couse it would be very annoying to write for all 100 fields, i need to know- how can i make to sum from all fields using just few lines of code!
