java设定窗口步长,依次统计窗口内数值总和

import java.util.Arrays;

public class test2 {

	public static void main(String[] args) {
		int winSize = 3;
		int moveStep = 2;
		int total = 9;

		System.out.println("样本为：");
		for(int i=0;i<total;i++){
			System.out.print(i+" ");
		}
		System.out.println("");
		System.out.println("窗口大小为："+winSize);
		System.out.println("步长大小为："+moveStep);

		int[] cycleArray = new int[winSize];
		int count = 0;
		int addPoint = winSize;
		// 参数初始化
		System.out.print("窗口{ ");
		for (int i = 0; i < winSize; i++) {
			cycleArray[i] = i;
			count += cycleArray[i];
			System.out.print(cycleArray[i]+" ");
		}
		System.out.print("}的数据总和为："+count);
		System.out.println("");

		for (int i = winSize; i < total; i = i + moveStep) {
			//先去除前moveStep项
			int add = addPoint;
			for (int j = 0; j < moveStep; j++) {
				count += (add+j);
				count -= cycleArray[addPoint % winSize];
				cycleArray[addPoint % winSize] = (add+j);
				addPoint++;
			}
			System.out.print("窗口{ ");
			int[] array = new int[winSize];
			for(int k=0;k<winSize;k++){
				array[k] = cycleArray[k];
			}
			for (int j = 0; j < winSize; j++) {
				Arrays.sort(array);  //进行排序
				System.out.print(array[j]+" ");
			}
			System.out.print("}的数据总和为："+count);
			System.out.println("");
		}
	}

}

　　

样本为：
0 1 2 3 4 5 6 7 8 
窗口大小为：3
步长大小为：2
窗口{ 0 1 2 }的数据总和为：3
窗口{ 2 3 4 }的数据总和为：9
窗口{ 4 5 6 }的数据总和为：15
窗口{ 6 7 8 }的数据总和为：21
