Avoiding imports

[jrs362]

For some reason, I have to rewrite a program to avoid using import statements. I know it's possible, but cannot seem to find it in my text book. Can someone please give me a sample outline of how it's done?

Thanks

in Java you can either specify the API package names using import statements or when you call the methods.

For example a program using import

import java.util.*;
import java.lang.*;
 
public class Test1
{
public static void main(String args[])
{
    Vector v = new Vector();
    v.addElement(Math.asin(1.0));
}
}
 

and same program using no import statements

public class Test
{
public static void main(String args[])
{
    java.util.Vector v = new java.util.Vector();
    v.addElement(java.lang.Math.asin(1.0));
}
}

Perhaps not related to the question but you do not have to import anything from java.lang. The package is automatically imported for you.
So you can just do
v.addElement(Math.asin(1.0));

using fully qualified names in the body is a bad coding practice. try not to do it
