Only one button is getting displayed in java awt -

i trying create display multiple buttons on it. however, 1 button being displayed. why happening? layout manager? did go wrong?

my code:

import java.awt.*; class buttondemo extends frame  {     button[] b;frame frame;     buttondemo()     {         int i=0;         b=new button[12];         frame=new frame();         frame.setlayout(new borderlayout());         (i=0;i<12;i++)         {             b[i] = new button("hello"+i);frame.add(b[i]);         }         frame.add(new button("hello"));         frame.add(new button("polo"));         frame.pack();         frame.setvisible(true);      }      public static void main(string args[])     {         buttondemo bd = new buttondemo();     } } 

this expected behaviour borderlayout.

borderlayout allow single component reside in each of it's 5 available positions.

you adding 2 buttons same position last 1 displayed.

try...

• adding 1 button borderlayout.north , borderlayout.south positions
• using different layout manager

take @ a visual guide layout managers , laying out components within container more details...
