clear console

i write this funtion to clear the console but it says thet clear not defined for console class


import java.lang.*;
import java.util.*;
import java.io.Console;

public void ClearConsole() {
Console console = System.console();
if (console == null)
System.out.println("Couldn't get Console object !");
console.clear();/////////// getting the error from this line
}

is there any other imports to write ???? or is there any other way to clear the console?
thx
