JRadioButtons not working

I'm having an issue where my JRadioButtons will not appear until moused over. I've looked up this issue before and it seems most people have solved it using layouts. However, I am not supposed to use them for my assignment, being completely new to graphics with Java I'm really struggling. Any ideas? Anything is appreciated.

import java.awt.GridLayout;

import javax.swing.*;
public class InsuarancePolicyApp {

public static void main(String[] args) {

//JFrame
JFrame f = new JFrame();
f.setVisible(true);
f.setSize(800, 600);
f.setLayout(null);
f.setResizable(false);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setTitle("Insurance Policy Application");

//JButtons
JButton addClient = new JButton("Add Client");
JButton openPolicy = new JButton("Open Policy");
f.getContentPane().add(addClient);
f.getContentPane().add(openPolicy);
openPolicy.setSize(300, 60);
addClient.setSize(380,60);
addClient.setLocation(30, 180);
openPolicy.setLocation(450, 180);

//JTextField
JTextField name = new JTextField("Name: ");
f.getContentPane().add(name);
name.setLocation(30,30);
name.setSize(380, 30);

//JList
String[] clientarray = {"Mark Mywords", "Jim Class", "Stan Dupp", "Mel Onhead", "Bob's Yoyo Shop", "Toys Aren't Us", "The Fish Rack"};
JList clients = new JList(clientarray);
f.getContentPane().add(clients);
clients.setLocation(30, 280);
clients.setSize(380, 250);

String[] policyarray = {"Policy 002354","Policy 005345", "Depreciable Policy 0789423", "Expirable Policy 009724"};
JList policies = new JList(policyarray);
f.getContentPane().add(policies);
policies.setLocation(450, 280);
policies.setSize(300, 250);


//JScrollPane
JScrollPane clientScroll = new JScrollPane(clients, ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS, ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED);
f.getContentPane().add(clientScroll);
clientScroll.setLocation(30,280); 
clientScroll.setSize(380,250);


JScrollPane policiesScroll = new JScrollPane(policies, ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS, ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED);
f.getContentPane().add(policiesScroll);
policiesScroll.setLocation(450,280); 
policiesScroll.setSize(300,250);

//JradioButons 
JRadioButton b1 = new JRadioButton("Company",false);
JRadioButton b2 = new JRadioButton("Individual",false);
JRadioButton b3 = new JRadioButton("Standard",false);
JRadioButton b4 = new JRadioButton("Depreciable",false);
JRadioButton b5 = new JRadioButton("Expirable",false);

//ButtonGroups
ButtonGroup clientsGroup = new ButtonGroup();
b1.setLocation(120, 70);
b1.setSize(100,30);
b2.setLocation(260, 70);
b2.setSize(100,30);
f.getContentPane().add(b2);
f.getContentPane().add(b1);
clientsGroup.add(b1);
clientsGroup.add(b2);


ButtonGroup policiesGroup = new ButtonGroup();
b3.setLocation(600, 10);
b4.setLocation(600, 60);
b5.setLocation(600, 110);
b3.setSize(100,60);
b4.setSize(100,60);
b5.setSize(100,60);
f.getContentPane().add(b3);
f.getContentPane().add(b4);
f.getContentPane().add(b5);
policiesGroup.add(b3);
policiesGroup.add(b4);
policiesGroup.add(b5);

//Jlabel
JLabel label = new JLabel("Type:");
f.getContentPane().add(label);
label.setLocation(30, 55);
label.setSize(60,60);

JLabel label2 = new JLabel("Type:");
f.getContentPane().add(label2);
label2.setLocation(545, 10);
label2.setSize(60,60);
}
}

The problem is that the JRadioButtons are not being painted as the JFrame has already been displayed when they are added.

You need to call JFrame#setVisible after you add all the components to the container:

f.setVisible(true);

Aside: Don't use absolute positioning (null layout), use a layout manager instead. Using a layout manager removes the need for the setting component sizes & positions.
