how to compare a Double Value in if statement in java?
<p>I have a desktop application with textboxs that contain a price values. As an example if i input 25000</p>

<pre><code>Double priceSec = Double.parseDouble(cusPrice.getText());
</code></pre>

<p>i'm passing that 25000 as a double value</p>

<p>so now i want to compare that value and check whether it is empty or not?</p>

<pre><code>if(cusPrice2.getText()==null || cusPrice2.getText().isEmpty()){
        Double priceSec=0.0;
        }
</code></pre>

<p>i know i can create an else condition for </p>

<pre><code>if textbox !=null
total=txtbox1+txtbox2+txtbox3;
</code></pre>

<p>if textbox value is empty or not empty. value should be there in total.
but  in my code ,it displays as null.</p>

<p>Do i have any other way to do that?
can you tell me a way to do that.</p>

<p>here is my full code</p>

<pre><code>  private void cusOkBtnActionPerformed(java.awt.event.ActionEvent evt) { 

    Double priceSec = Double.parseDouble(cusPrice2.getText());
    Double priceThird = Double.parseDouble(cusPrice3.getText());
    Double priceFourth = Double.parseDouble(cusPrice4.getText());
    Double priceFifth = Double.parseDouble(cusPrice5.getText());

    if(cusPrice2.getText()==null || cusPrice2.getText().isEmpty() || cusPrice2.getText() !=null ){
            priceSec=0.0;
            costCls.setItemPrice(priceSec);
            }
            else if(cusPrice3.getText()==null || cusPrice3.getText().isEmpty()){
            priceThird=0.0;
            }
            else if(cusPrice4.getText()==null || cusPrice4.getText().isEmpty()){
            priceFourth=0.0;
            }
            else if(cusPrice5.getText()==null || cusPrice5.getText().isEmpty()){
            priceFifth=0.0;
            }

           Double setItemTotal = priceCus+priceSec+priceThird+priceFourth+priceFifth;

}
</code></pre>
