Yesterday there was someone in Facebook Java Group asked how to get selected value from RadioButton in Java Swing. Actually this problem is very easy to be solved, but since in the past i didn’t learn Swing in depth and never use RadioButton except in web based projects which are on different side so i took a search on google and read some books 😀

We need to locate RadioButton inside ButtonGroup so that RadioButton works as group not individually because RadioButton’s behavior is can be selected just one in one group. Moreover we have to set the action command for RadioButton, this is like the value of it. So here’s my solution
Suppose you design the Frame using Netbeans GUI Builder
When jButton is clicked, jLabel1 will show whether “male” or “female” depends on your choice.
2 4 6 8 10 | publicMainFrame(){ jRadioButton2.setActionCommand('Female'); buttonGroup=newButtonGroup(); buttonGroup.add(jRadioButton2); |
As i mentioned above, we set the action command and place RadioButton inside ButtonGroup. To get the value of your choice simply using buttonGroup object.
2 4 6 8 10 | publicMainFrame(){ jRadioButton2.setActionCommand('Female'); buttonGroup=newButtonGroup(); buttonGroup.add(jRadioButton2); |
2 4 6 8 10 | publicMainFrame(){ jRadioButton2.setActionCommand('Female'); buttonGroup=newButtonGroup(); buttonGroup.add(jRadioButton2); |
