java 语言实现插入排序

public class InsertSort{
	public static void main(String[] args){
		int[] sortArray = new int[]{5,7,4,2,9,8,3,6};
		System.out.println("before sorting ,the numbers are:");
		show(sortArray);
		insertSort(sortArray);
		System.out.println("after sorting,the numbers are:");
		show(sortArray);
	}
	public static void insertSort(int[] intArray){
		for(int i=1;i<intArray.length;i++){
			int a = intArray[i];
			for(int j = i-1;j>=0;j--){
				if(intArray[j]>a){
					int temp = intArray[j];
					intArray[j] =intArray[j+1];
					intArray[j+1] = temp;
				}else{
					break;
				}
			}
		}
	}
	public static void show(int[] intArray){
		for(int i=0;i<intArray.length;i++){
			System.out.print(intArray[i]+"\t");
		}
		System.out.println();
	}
}
