多维数组的实现 (java 表示)

public class MultiDimArray {    private static int MAX_ARRAY_DIM = 8;//数组最大维数    int[] base;//数组元素基地址    int dim;//数组维数    int[] bounds; //数组维界基地址    int[] constants;//数组映像函数 常量基址    //初始化n维数组    public void initArray(int dim,int... args) {        print("dim:"+dim);        if(dim < 1 || dim > MAX_ARRAY_DIM) {            System.out.println("dim is illegal");            return;        }        this.dim = dim;        this.bounds = new int[dim];        int elemtotal = 1;//求出数组元素的总数        if(args.length != dim) {            System.out.println("args is illegal");            return;        }        for(int i = 0; i < dim; i++) {            this.bounds[i] = args[i];            elemtotal*= this.bounds[i];        }        this.base = new int[elemtotal];        //求映像函数常数Ci        this.constants = new int[dim];        this.constants[dim -1] = 1;        for(int i = dim -2; i >= 0; i--) {            this.constants[i] = this.bounds[i+1]*this.constants[i+1];        }        for(int i = 0; i < this.constants.length; i++) {            print("constants["+i+"]="+constants[i]);        }    }    //销毁n维数组    public void destroyArray() {        this.base = null;        this.bounds = null;        this.constants = null;        this.dim = 0;    }    //求元素在多维数组的相对地址off    public int locate(int ...index ) {        int off = 0;        for(int i = 0; i < dim; i++) {            int ind = index[i];            off+=constants[i]*ind;        }        print("locate:"+off);        return off;    }    //获取n维数组某个元素的值    public int value(int ... index) {        int result = locate(index);        if(result <= 0) {            return result;        }        return this.base[result];    }    //给n维数组 某个下标元素赋值    public void assign(int value,int ... index) {        int off = locate(index);        if(off <= 0) {            return ;        }        this.base[off] = value;    }    private void print(String str) {        System.out.println(str);    }}package com.gac;public class Test {    public static void  main(String[] args) {        MultiDimArray dimArray = new MultiDimArray();        dimArray.initArray(3, 4,2,3);        dimArray.locate(1,2,1);        dimArray.assign(15, 1,1,2);        print("value:"+dimArray.value(1,2,2));    }    public static void print(String str) {        System.out.println(str);    }}
