java - Quick Advice with GUI simple alignment? -

i'm new java , got assignment. have create math frame operations , has gui formatted way. can except 3 textfields stacked on top. this:

t1 t2 t3  

these 3 go down on left vertically, while other 4 boxes across bottom.

where t1, t2 , t3 textfields , 1, 2, 3 , 4 functions of operation.

i can't x, y , z on left. here's code, please if can!

convert.java:

import javax.swing.jframe;  public class convert {     public static void main(string[] args) {         convertframe convertframe = new convertframe();         convertframe.setdefaultcloseoperation(jframe.exit_on_close);         convertframe.setsize(500, 400); // set frame size         convertframe.setvisible(true); // display frame     } } // end class 

if want stack textfields on top

you should change

panel2.setlayout(new gridlayout(1, 5)); 

to this

panel2.setlayout(new gridlayout(5, 1)); 

because in new gridlayout(row, column) first argument row count , next 1 column count .currently have 1 row , 5 columns.so text field positioned coulmns .if want position vertically should use 1 column , 5 rows
