直接插入排序 java

public class InsertionSort{public static void main(String args[]){int a[]={78,43,56,89,0,12,34,123,567,98,53};for(int i=0;i<a.length-1;i++){int index=a[i+1];for(int j=i;j>=0;j--){if (index<a[j]){a[j+1]=a[j];a[j]=index;}else{a[j+1]=index;break;}}}for (int z=0;z<a.length;z++){System.out.print(a[z]+"/");}}}
