Exercise 1: Generic Types in Java The Java class below defines a new type, a pair of double values. Rewrite this class as a generic type PairT>. Test your generic class by making a ParString> object and printing its contents. public class Pair private double ele1; private double ele2; el; ele2 = e2; } public Pair(double e1, double e2) { elel public double ele1() return ele1; ) public double ele2() return ele2; @0verride public String tostring) return "(" elel "," + ele2 + ")"; ) /ITEST CLIENT // public static void main(String[] args) f Pair p-new Pair(1.0,2.0); System.out.println(p);Explanation / Answer
public class Pair<T> {
private String ele1;
private String ele2;
public Pair(String e1,String e2) {
ele1=e1;
ele2=e2;
}
public String ele1() {
return ele1;
}
public String ele2() {
return ele2;
}
@Override
public String toString() {
// TODO Auto-generated method stub
return "("+ ele1 +","+ ele2 +")";
}
/**
* @param args
*/
public static void main(String[] args) {
Pair<String> p=new Pair<String>("hi", "java");
System.out.println(p);
}
}
