    Post vending machine submit button help

    Hi ,
    I have created a submit button "sbutton" that should take all totals from 3 boxes and if that total is greater than 1, then it should be subtracted from 1 and the remainder is suppose to be displayed as change...this is what i have
    public void actionPerformed(ActionEvent evt) {
    if(evt.getSource()==sButton){
    change.setText(---"I DON"T KNOW WHAT TO PUT HERE")
    selections.setText("Vending....");

    and in another class to add up the 3 totals i have
    public String total5(){
    	total5=total+total2+total3+total4;
     
    	String blank =new String();
    	blank="$"+total5;
    		return blank;
     
     
     
    }

    so my question is how do i use the total5 to compare if it's over 1 or less and display if it's over in the "change.setText( )" text box?

    Also note that this kind of coding is NEVER required;
    	String blank =new String();
    	blank="$"+total5;
    		return blank;
    That should be
    	return "$"+total5;
    db
