I need the method implementation for this interface using java. The interface must not be changed in any way from what is seen below.

it will be used to set and get counts of digits and chars from a plain string. But you must not pass the string to the interface methods.

public interface Message // set the counts for characters and digits public void set Counts(); // return the number of characters public int getCharacterCount(); // return the number of digits public int getDigitCount(); }
