排序-冒泡排序

public class Bubble {
    public static void sort(Comparable[] a){

        for(int i=a.length-1;i>0;i--){
            for(int j=0;j0;
    }



    private static void exch(Comparable[] a,int i,int j){
        Comparable temp;
        temp=a[i];
        a[i]=a[j];
        a[j]=temp;
    }
}

//测试类

import java.util.Arrays;

public class BubbleTest {

    public static void main(String[] args) {

       Integer[] arr={4,5,2,6,1,3};
       Bubble.sort(arr);

        System.out.println(Arrays.toString(arr));
    }
}
