Assume that word is a variable of type string that has been assigned a value. Assume furthermore that this value always contains the letters “”dr”” followed by at least two other letters. For example: “undramatic”,”dreck”, “android”, “no-drip”. Assume that there is another variable declared, drWord, also of type string. Write the statements needed so that the 4-character substring word of the value of word starting with “dr” is assigned to drWord. So, if the value of word were ” George slew the dragon” your code would assign the value “drag” to drWord.

    class Test {
    public static void main(String [] args){

    String word=”George slew the dragon”;
    int first=word.indexOf(“dr”);

    String drWord=word.substring(first,first+4);

    System.out.println(drWord);

    }

    }
