How to use ToolTip in Java Swing

You can create a tool tip for any JComponent with setToolTipText() method. This method is used to set up a tool tip for the component.

For example, to add tool tip to PasswordField, you need to add only one line of code:

Simple ToolTip Example

import javax.swing.*;  
public class ToolTipExample {
	public static void main(String[] args) {  
	 JFrame f=new JFrame("Password Field Example");  
	 //Creating PasswordField and label
	 JPasswordField value = new JPasswordField(); 
	 value.setBounds(100,100,100,30);  
	 value.setToolTipText("Enter your Password");
	 JLabel l1=new JLabel("Password:");  
	 l1.setBounds(20,100, 80,30);  
	 //Adding components to frame
	 f.add(value);  f.add(l1);
	 f.setSize(300,300);  
	 f.setLayout(null);  
	 f.setVisible(true);   	
}
}
