Thread: Jlabel won't clear

Hello, I am trying to clear a jlabel so I can put the current page number up. Instead it writes each number right after another and the jlabel won't clear. I am using setText("") Here is the relevant code, if you need more code I can put up the entire program.

private class ButtonHandler implements ActionListener {       public void actionPerformed(ActionEvent e)   { formatter8.format("%d",Page);   JButton button = (JButton) e.getSource();   if(button.equals(previousJButton)) //firstButton is the first class JButton that was defined   { if(Page==1){ //JOptionPane.showMessageDialog(DataEntry.this,String.format("You pressed: %s",e.getActionCommand())); label1.setText(formatter.toString());	label2.setText(formatter2.toString());	label3.setText(formatter3.toString());	label10.setText(formatter8.toString());   } Page--; if(Page<0) {	Page=0;	label10.setText(formatter8.toString());     } if(Page==0){ label1.setText(formatter.toString()); label2.setText(formatter2.toString());  	label3.setText(formatter3.toString()); formatter8.format("%d",Page);    	label10.setText(formatter8.toString());     } if(Page==1){	label1.setText(formatter5.toString()); label2.setText(formatter6.toString());	label3.setText(formatter7.toString());	label10.setText("");	label10.setText(formatter8.toString());   }     }   if(button.equals(nextJButton)) //secondButton is the second class JButton defined   { Page++; if (Page==1){ //Panel5.removeAllChildComponents(). label1.setText(formatter5.toString());	label2.setText(formatter6.toString());	label3.setText(formatter7.toString()); label10.setText(""); label10.setText(formatter8.toString());   } else{  	label10.setText("");	label10.setText(formatter8.toString()); }   }     }   }

This is the shortened program, below it is the test program which I keep in another java file. I will comment at the problem section.
