Question

 Write a generic class called Trio that has one type parameter.  It contains an array of three elements of the type parameter's type.  It contains three methods, first() and second(), and third(), that return one of the three items respectively.  Include a main method in the class which creates a Trio object with a String type.  The object should be created with three strings:  "abc", "def", "ghi".  Use the first(), second(), and third() methods to get each string from the Trio object and print it

Explanation / Answer

publicclass Trio { private AnyType[]array; publicTrio(AnyType a1, AnyType a2, AnyType a3) { array=(AnyType[])(newObject[3]); array[0]=a1; array[1]=a2; array[2]=a3; } public AnyTypefirst() { return array[0]; } public AnyTypesecond() { return array[1]; } public AnyTypethird() { return array[2]; } } // code in main Trio test = new Trio("abc","def", "ghi"); System.out.println(test.first()); System.out.println(test.second()); System.out.println(test.third());
