How to clear all textfield of jframe using loop?

java, jframe, jtextarea, jtextfield, swing

Solution

Iterate over all of the components and set the text of all `JTextField` and `JTextArea` objects to an empty String:

//Note: "this" should be the Container that directly contains your components
//(most likely a JPanel).
//This won't work if you call getComponents on the top-level frame.
for (Component C : this.getComponents())
{    
    if (C instanceof JTextField || C instanceof JTextArea){

        ((JTextComponent) C).setText(""); //abstract superclass
    }
}

Problem

I'm developing Java application using NetBeans. I have 5 `JTextFields` and 2 `JTextArea` in `JFrame`. I want to clear them at once using a loop. How can it be done?
