How to clear all textfield of jframe using loop?
10,016
Solution 1
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
}
}
Solution 2
The appropriate code should be this one
Component[] components = jframe.getContentPane().getComponents();
for (Component component : components) {
if (component instanceof JTextField || component instanceof JTextArea) {
JTextComponent specificObject = (JTextComponent) component;
specificObject.setText("");
}
}
