Hi my question is why doesn't the Console work in eclipse. I tried using it but the compiler is showing an error.

public class Console {

public static void main(String[] args) {
        Console console = System.console();
        console.printf("Abdi");
}

}

I hope you have found the solution to your problem, if not;

According to your code: import java.io.Console; public class input { public static void main(String[] args) { Console console = System.console(); console.printf("this is printf"); } }

the name of your public class is "input", so save your file as "input.java" and it should work fine.

Have you imported java.io.Console? If not add the following to the very top:

import java.io.Console;

Eclipse is pretty good at giving you feedback about errors, it should underline any errors in red. If you see any red lines hover over them and it'll give you some feedback, possibly telling you how to fix the error. Although remember Eclipse doesn't know what you're doing, some of the fixes will just suppress the error, not fix the problem in an appropriate way, so it's always good to ask or Google. :)
