java实现链栈在前面有所介绍:http://www.cnblogs.com/lixiaolun/p/4644141.html
将前面java实现链栈的代码稍作修改:
package linkedstack; public class LinkStack { private Element base; private Element top; class Element { public Object data; public Element next; } /** * 初始化栈 * */ public void initStack() { top = new Element(); base = new Element(); top.data=null; top.next=base; base.data=null; base.next=null; } /** * 入栈 * */ public void push(Object o) { Element e = new Element(); e.data = o; if(top.next==base)//第一次入栈操作 { e.next=base; top.next=e; }else { e.next=top.next; top.next=e; } } /** * 出栈 * */ public Object pop() { Object o = null; if(top.next==base) { System.out.println("栈中没有元素!"); return o; }else { o = top.next.data; //System.out.println("出栈操作"+o); top.next=top.next.next; } return o; } /** * 判断栈是否为空 * */ public Boolean isEmpty() { if(top.next==base) { return true; } return false; } /** * 打印栈 * */ public void print() { System.out.print("打印栈:"); Element temp =top; while(temp.next!=base) { System.out.print(temp.next.data+"\t"); temp =temp.next; } System.out.println(); } }
java实现数制转换的类的代码:
package stackapplication; import linkedstack.LinkStack; public class Conversion { public static void main(String[] args) { LinkStack lStack = new LinkStack(); lStack.initStack(); int N = 100;//原始十进制数 int X = 2;//要转化成X进制数 while(N!=0) { lStack.push(N%X); N=N/X; } while(!lStack.isEmpty()) { System.out.print(lStack.pop()); } } }
