(学习java) 线性表的顺序存储

//10-10 今天看了数据结构中线性表的顺序存储结构部分,用java代码写了一个简单的结构public class LineList {int maxsize = 20;String[] data = new String[maxsize];int length;public static void main(String[] args) {LineList L = new LineList();L.length = 0;mean M = new mean();M.ListInsert(L, 1, "a");M.ListInsert(L, 2, "b");M.ListInsert(L, 3, "c");//M.List(L);String e = M.ListDelete(L, 2);System.out.println(e);M.List(L);}}class mean{//线性表的插入public int ListInsert(LineList L,int i,String e){if(L.length == L.maxsize){return 0;}if(i<0){return 0;}if(i>L.length){L.data[L.length] = e;L.length++;return 1;}if(i<=L.length){for(int k=L.length-1;k<i;k--){L.data[k+1] = L.data[k];}}L.data[i-1] = e;L.length=+1;return 1;}//线性表元素的获取public int GetElem(LineList L, int i, String e){if(i<0 || i>L.length){return -1;}e = L.data[i-1];return 1;}//线性表删除public String ListDelete(LineList L,int i){if(i<0 || i>L.length){return "Error";}else{String e = L.data[i-1];for(int k = i;k<L.length;k++){L.data[k-1] = L.data[k];}L.length--;return e;}}//线性表遍历public void List(LineList L){for(int i=0;i<L.length;i++){System.out.println(L.data[i]);}}}
