Question

Problem 21.4: Write a generic method selectionSort based on the sort program of Figs. 19.6-19.7. Write a test program that inputs, sorts and outputs and Integer array and a Float array. [Hint: Use <T extends Comparable <T>> in the type-parameter section for method selectionSort, so that you can use method compareTo to compare the objects of the type that T represents.

Explanation / Answer

//Needed ArrayIndexOutOfBoundException import java.lang.ArrayIndexOutOfBoundsException; //Create class GenericSelectionSort public class GenericSelectionSort { //Main Method     public static void main(String[] args){         try{         // Create an array of Integers         Integer [] num = {90,120,30,20,10,60};         // Display Message        System.out.println("Integer Elements after sorting ");       // Method for sort integer numbers       selectionSort(num);            //catch the exception          }catch (ArrayIndexOutOfBoundsException e1){          }         try{             //Create an array of float or double values              Double [] num1={12.9,11.8,87.9,10.1,6.9};       System.out.println(" Float Elements after sorting ");       //method to sort double values       selectionSort(num1);       //catch the exception       }catch (ArrayIndexOutOfBoundsException e2){       }            } // Method to sort the elements in the array public static void selectionSort(T[] list) { for (int i = 1; i = 0 && list[j].compareTo(Element) > 0; j--) {         list[j+ 1] = list[j];       }       // Insert the current element into list[k+1]       list[j + 1] = Element;     } //For loop prints the sorted elements for(int i=0;i
