How to execute Arithmetic Exception catch block in Java?

This is the code snippet:

public void actionPerformed(ActionEvent e){
        int i1,i2;

        try{
            if(e.getSource()==b1){
            .
            .
            .

            else if(e.getSource()==b4){
                double i1,i2;
                i1=Integer.parseInt(t1.getText());
                i2=Integer.parseInt(t2.getText());
                i1=i1/i2;
                l7.setText(i1+"");
            }
            else if(e.getSource()==b5){
                i1=Integer.parseInt(t1.getText());
                i2=Integer.parseInt(t2.getText());
                i1=i1%i2;
                l7.setText(i1+"");
            }
        }
        catch(ArithmeticException ex2){
            l7.setText("Debugging?");
            JOptionPane.showMessageDialog(null,"Divide by zero exception!!");
            //*WHY THIS SECTION IS NEVER BEING EXECUTED AFTER PERFORMING A DIVIDE BY ZERO i.e. ARITHMETIC EXCEPTION!*
        }
        catch(Exception ex){
            JOptionPane.showMessageDialog(null,"Enter Values First!!");
        }
    }

The JRE is never executing the Arithmetic Exception catch statement, why?

Yes, it is handing it but it not producing the output that I expect it to produce! It is automatically displaying, "Infinity" & "NaN" on my Java application! Thanks!

Yes! Double and float have their own inbuilt values for infinity. There might be some other issues in your code that I'm not aware about.

Check these edits:

else if(e.getSource()==b4){
            double i1,i2;
            i1= Integer.parseInt(t1.getText());
            i2= Integer.parseInt(t2.getText());
            if(i1!=0 && i2 == 0){
                throw new ArithmeticException();
            }
            else if(i2 == 0 && i1 == 0) {
                throw new ArithmeticException();
            }
            i1= i1/i2;
            l7.setText(i1+"");
        }

This throw new ArithmeticException(); will force your code to execute the section that you are willing to execute!

Hope this helps!
