Static import

All the static members are accessed by using the ClassName. By using static import we can call the variable or method with name itself, no need to call the members with ClassName as prefix.

Without using static import

import java.lang.Math;
class WithOutStaticImport{
 public static void main(String args[]){
  System.out.println("Square root of 100 is " + Math.sqrt(100));
 }
}

Output

Square root of 100 is 10.0

With static import

import static java.lang.Math.*;
class WithStaticImport{
 public static void main(String args[]){
  System.out.println("Square root of 100 is " + sqrt(100));
 }
}

Output

Square root of 100 is 10.0
