sortfactory.java

用java写的

package oop;

import java.util.Scanner;

//控制Sort实例的创建,当添加一个新Sort类型时只需要修改改类
public class SortFactory {
	
	public static Sort createSort(){
		Scanner scan=new Scanner(System.in);
		System.out.println("请选择排序方法:\n"
				            +"  1.插入排序\n"
				            +"  2.选择排序\n"
				            +"  3.冒泡排序\n"
				            +"  4.快速排序\n"
				            +"  5.堆排序\n");
		int i=scan.nextInt();
		switch(i){
		case 1:
			System.out.println("经插入排序后:\n");
			return InsertionSort.getInstance();
		case 2:
			System.out.println("经选择排序后:\n");
			return SelectionSort.getInstance();
		case 3:
			System.out.println("经冒泡排序后:\n");
			return BubbleSort.getInstance();
		case 4:
			System.out.println("经快速排序后:\n");
			return QuickSort.getInstance();
		case 5:
			System.out.println("经堆排序后:\n");
			return HeapSort.getInstance();
		default:
			System.out.println("经插入排序后:\n");
			return InsertionSort.getInstance();
		}
	}
