i suspect print
hello avax.swing.jtextfield[,0,0,0x0,invalid,layout=javax.swing.plaf.basic.basictextui$updatehandler,alignmentx=0.0,alignmenty=0.0,border=javax.swing.plaf.borderuiresource$compoundborderuiresource@58372a00,flags=296,maximumsize=,minimumsize=,preferredsize=,caretcolor=sun.swing.printcoloruiresource[r=51,g=51,b=51],disabledtextcolor=javax.swing.plaf.coloruiresource[r=184,g=207,b=229],editable=true,margin=javax.swing.plaf.insetsuiresource[top=0,left=0,bottom=0,right=0],selectedtextcolor=sun.swing.printcoloruiresource[r=51,g=51,b=51],selectioncolor=javax.swing.plaf.coloruiresource[r=184,g=207,b=229],columns=0,columnwidth=0,command=,horizontalalignment=leading] you've still got lot of livin' left do!
or such.
this because you're using
jtextpane1.settext("hello " + jtextfield1 + "\n you've still got lot of livin' left do!"); which automatically calls jtextfield1's tostring method (nice feature when you're use it).
instead should using jtextfield#gettext text field contains, example...
jtextpane1.settext("hello " + jtextfield1.gettext() + "\n you've still got lot of livin' left do!"); the other problem is, there nothing calling jbutton1actionperformed method print anything.
you need attach actionlistener buttons , have them call method update text...
for example...
jbutton1.addactionlistener(new actionlistener() { @override public void actionperformed(actionevent e) { jbutton1actionperformed(e); } }); you'll need each button...
now, suggest put away form designer , take time read through creating gui jfc/swing. give greater appreciation of how swing guis created , how tool form designer can used.
learn cut wood saw before use bandsaw...otherwise you're loose limbs ;)
