1.1 Write a Java program which stores a pair of values and support following methods: getFirst, getSecond, setFirst and setSecond. (100 points) 1. Define a Pair class that has: Two elements (first, second), A constructor and Four 2. methods(getFirst, getSecond, setFirst and setSecond). Implement test class TestPair that Define an array(length is 10) of Pair type. • Type of first - int, type of second - double. Set the value of array.first: (0, 1, 2, ..., 8, 9). Set the value of array.second: (9.0, 8,0, ..., 1.0, 0.0). Print out the array. ● ● 1.2 Please Modify the homework1.1 by using Java Generics. (Declare two elements by using formal type parameters).
