        input.addActionListener(this);
        c.add(promt);
        c.add(input);
    public int calculateCharges(int hrs){
        if ( (hrs>=0) && (hrs<=3) && (hrs != 24) ){
        total = 2*hrs;   
        if((hrs>=3)&& (hrs<24) && (hrs != 24)){
        total = (int) (((hrs - 3) * 0.50) + 6);
        if (hrs == 24){
            total = 10;
        return total;
    public void actionPerformed(ActionEvent e) {
        int hrs = Integer.parseInt(e.getActionCommand());
        showStatus ("You have to pay:"+calculateCharges(hrs));
}

Answer 1

...because changing this:
public class MoneyCollect extends JFrameto this:
public class MoneyCollect extends JAppletdoes not create an applet. Get a beginning java book and start reading it. I recommend "Java2: A Beginner's Guide".
Or, you can read the following tutorial to learn why your program is not an applet:
