import statement

import statement: import statement is similar to the #include statement in C.  Using the import statements, we can access to classes that are part of other packages.

            Example:         import javax.swing.JOptionPane;

This statement instructs that the interpreter to load the JOptionPane class contained in the javax.swing package.

Example:

import javax.swing.JOptionPane;

class ch

{

            public static void main(String[] args)

            {

            String sn1;

            int x;

            sn1=JOptionPane.showInputDialog("Enter x value");

            x=Integer.parseInt(sn1);

JOptionPane.showMessageDialog(null,"value="+x,"output",JOptionPane.ERROR_MESSAGE);}

}
