java - Using an array to store values from a GUI -

i having problem controlgui class. want create array store integer values of data entered on gui jtextfield , return input use in a different class. code is:

public class controlgui extends jframe{  private temperaturecontrolagent myagent;*emphasized text*  public static jtextfield mouldtempfield, melttempfield;  public controlgui() {  }   public static int[] getarray(){   int input[] = new int [2];  jtextfield t[]=new jtextfield [10];  //public textfieldarray  jpanel panel=new jpanel(new gridlayout(5,2)); for(int i=0;i<10;i++)  {  t[i]= new jtextfield(10); panel.add(t[i]);    input[0] = integer.parseint(mouldtempfield.gettext());   input[1] = integer.parseint(melttempfield.gettext());   system.out.println("input mouldtempfield"+ input[0]);     return input;}   controlgui (temperaturecontrolagent a)  {     super (a.getlocalname());      myagent = a;        jpanel p = new jpanel();     p.setlayout(new gridlayout (3, 3));     p.add(new jlabel ("mould temperature set value: "));     mouldtempfield = new jtextfield (10);     p.add(mouldtempfield);     p.add(new jlabel ("melt temperature: "));     melttempfield = new jtextfield (10);     p.add(melttempfield);     getcontentpane().add(p, borderlayout.center);       jbutton addbutton = new jbutton ("enter");     addbutton.addactionlistener (new actionlistener() {          @override             public void actionperformed(actionevent ev) {         try {              string mouldtemp = mouldtempfield.gettext().trim();             string melttemp = melttempfield.gettext().trim();              myagent.updatecatalogue(integer.parseint(mouldtemp), integer.parseint(melttemp));              mouldtempfield.settext("");             melttempfield.settext("");          }                    catch (exception e) {         joptionpane.showmessagedialog(controlgui.this, "invalid values. "+e.getmessage(), "error", joptionpane.error_message);         }        }     });        p = new jpanel();     p.add(addbutton);     getcontentpane().add(p, borderlayout.south);         //ensure termination of agent when user closes gui     //using "close" button     addwindowlistener(new windowadapter() {     @override          public void windowclosing(windowevent e) {          myagent.dodelete();          }     });      setresizable(false);   } public void showgui(){     pack ();     dimension screensize;   screensize = toolkit.getdefaulttoolkit().getscreensize();     int centerx = (int)screensize.getwidth() / 2;     int centery = (int) screensize.getheight() / 2;     setlocation(centerx - getwidth() / 2, centery - getheight() / 2 );     super.setvisible(true);  }    } 

i getting java.lang.numberformatexception error line 39 , 40 on code, when try extract integer value of inputed on jtextfield. stuck , not know do. in advance

this error occurred because 1 of jtextfield has bot int value, need catch exception like:

 try {       input[0] = integer.parseint(mouldtempfield.gettext().trim());//use trim remove white spaces.  } catch(numberformatexception e) {       //handle exception          }
