Java Static Import

Java Static Import: state the definition in one sentence. For Java Static Import, know the key keywords / API types involved.

Be ready with one tiny runnable Java Static Import example.

Mention one common Java Static Import mistake and the fix.

Write one tiny example for Static Import. Compile, print one result, and say the output out loud before you type.

Use Static Import only when the problem needs it. Don’t force it into every program. Know one beginner trap.

Let's take this on the board with one tiny Main class — no extra files. Java Static Import — output: 15 then 3.14159…. import static lets you write max and PI without Math. Start from main, go line by line, and stop at each print. That output is the proof for Static Import.

Exam tip

Explain Java Static Import as: definition → why → one code idea.

Example

import static java.lang.Math.max;
import static java.lang.Math.PI;
public class Main {
  public static void main(String[] args) {
    System.out.println(max(8, 15));
    System.out.println(PI);
  }
}

Java Static Import — output: 15 then 3.14159…. import static lets you write max and PI without Math.
