Java Multidemensional Array Loop that inputs data with Button Action -

questions pulling hair out over.

how array add together info current index, increment next index add together changed jtextfield info next button press. i'm overwriting same index.

i have tried figure out actionlisteners button "submit" uses counter nesting of loop. played ideas question 23331198 , 3010840 , 17829577 many others reference didn't far. searches pull info on managing buttons arrays , creating button arrays assume i'm not using right wording search with. have read few places md array not best alternative use.

this looking help!

import java.awt.event.actionevent; import java.awt.event.actionlistener; import javax.swing.jbutton; import javax.swing.jframe; import javax.swing.jlabel; import javax.swing.jpanel; import javax.swing.jtextarea; import javax.swing.jtextfield; public class guiandlogictest extends jframe { // variable decloration private static jframe mainframe; private static jpanel mainpanel; private static jtextfield fieldone; private static jtextfield fieldtwo; private static jtextarea textarea; private static jlabel textfieldonelabel; private static jlabel textfieldtwolabel; double[][] tutarray = new double[10][2]; int arrayindex = 0; // int =0 ; // set gui method private void gui() { // constructs gui mainframe = new jframe(); mainframe.setsize(800, 800); mainframe.setresizable(false); mainframe.setdefaultcloseoperation(jframe.exit_on_close); mainpanel = new jpanel(); textfieldonelabel = new jlabel("number 1"); mainpanel.add(textfieldonelabel); fieldone = new jtextfield(10); mainpanel.add(fieldone); textfieldtwolabel = new jlabel("number 2"); mainpanel.add(textfieldtwolabel); fieldtwo = new jtextfield(10); mainpanel.add(fieldtwo); textarea = new jtextarea(50, 50); mainpanel.add(textarea); jbutton exit = new jbutton("quit");// quits programme mainpanel.add(exit); exit.addactionlistener(new actionlistener() { @override public void actionperformed(actionevent e) { system.exit(0); } }); jbutton submit = new jbutton("enter"); // reads jfields , set varibles submitted array mainpanel.add(submit); submit.addactionlistener(new actionlistener() { @override public void actionperformed(actionevent arg0) { double txtfield1 = double .parsedouble(fieldone.gettext().trim()); double txtfield2 = double .parsedouble(fieldtwo.gettext().trim()); textarea.settext(""); if (txtfield1 < 0) { } if (txtfield2 < 0) { } tutarray[arrayindex][0] = txtfield1; tutarray[arrayindex][1] = txtfield2; arrayindex++; (int = 0; < arrayindex; i++) { textarea.append("number1: " + tutarray[i][0] + " number2: " + tutarray[i][1]); // textarea.append("\n"); //textarea.append(string.valueof(arrayindex++)); textarea.append("\n"); // textarea.append(string.valueof(arrayindex++)); } } }); jbutton study = new jbutton(); // used pull info out of array formatting , math mainframe.setvisible(true); mainframe.add(mainpanel); } public static void main(string[] arg) { guiandlogictest guiandlogic = new guiandlogictest(); guiandlogic.start(); } public void start() { gui(); } }

you can add together index field in main object:

protected int index;

in actionperformed increment index:

index++;

note:

but why extend jframe , utilize field mainframe?

you can utilize

this.setsize(800,800); this.add(mainpanel);

please declare (because of extends jframe):

private static final long serialversionuid = 1l;

please start name of object lower case letter:

jbutton exit = new jbutton("quit");

java arrays for-loop jbutton
