java - declaring a variable textfield -

i trying declare jtextfield variable name

for fixed jtextfield declare after public class as

private jtextfield hh1; 

but variable text field trying create them within

int count = 1 hh + count++ = new jtextfield(10); 

this within private class

private void creategui() { setdefaultcloseoperation(exit_on_close); container window = getcontentpane(); window.setlayout(new gridbaglayout());  gridbagconstraints gbc = new gridbagconstraints(); gridbagconstraints gbc1 = new gridbagconstraints(); gbc.fill = gridbagconstraints.both; gbc.insets = new insets(5, 50, 5, 0); gbc1.insets = new insets(5, -100, 5, 10); int count = 1; for(int y = 0; y < 10; y++) { gbc.gridy = y; gbc1.gridy = y; for(int x = 0; x < 1; x++) { gbc.gridx = x; gbc1.gridx = x;  vol1hh + count++ = new jtextfield(10); hh1 = new jlabel("hh1"); window.add(hh1 + count++, gbc1); window.add(vol1hh + count++, gbc); }     

how can create variable jtextfields called hh1 hh10?

answer below

private jtextfield vol1hh[] = new jtextfield [10];  private void creategui() { setdefaultcloseoperation(exit_on_close); container window = getcontentpane(); window.setlayout(new gridbaglayout());   gridbagconstraints gbc = new gridbagconstraints(); gridbagconstraints gbc1 = new gridbagconstraints(); gbc.fill = gridbagconstraints.both; gbc.insets = new insets(5, 50, 5, 0); gbc1.insets = new insets(5, -100, 5, 10); //int count = 1; for(int y = 0; y < 10; y++) { gbc.gridy = y; gbc1.gridy = y; for(int x = 0; x < 1; x++) { gbc.gridx = x; gbc1.gridx = x;  vol1hh[y] = new jtextfield(10);  window.add(vol1hh[y], gbc);   } 

in code not following rules declare variable. variable name cannot contain +, , neither name of variable dynamic.

if know how many jtextfield need in case best approach use array of jtextfield.

private jtextfield hh[] = new jtextfield[10]; int count = 0 hh[count++] = new jtextfield(10); 

and if don't know how jtextfield need use list idea.

private arraylist<jtextfield> hh = new arraylist<>(); int count = 0; hh.add(new jtextfield(10));
