Wan import statement in Java is used to −
Import user defined classes/Interfaces

import java.lang.Math.*;
public class Sample{
public static void main(String args[]){
System.out.println(Math.sqrt(169));
}

In case of static imports
static import allows to access the static members of a class without class qualifications. For Example, to access the static methods you need to call the using class name &minsu;
Math.sqrt(169);
But, using static import you can access the static methods directly.
Example
import static java.lang.Math.*;
public class Sample{
public static void main(String args[]){
System.out.println(sqrt(169));
}
}
Output
13.0
