关于数据结构（java）的一个代码

描述栈抽象数据类型的SStack接口的声明

public interfaceSStackE //栈接口

{

boolean isEmpty(); //判断是否空栈，若空栈返回true

boolean push(E element); //元素element入栈，若操作成功返回true

E pop(); //出栈，返回当前栈顶元素，若栈空返回null

E get(); //取栈顶元素值，未出栈，若栈空返回null

}

顺序栈类具体操作方法的声明：

importdataStructure.linearList.SStack;

public classSeqStackE implements SStackE

//顺序栈类

{

private Object value[]; //存储栈的数据元素

private int top; //top为栈顶元素下标

public SeqStack(int capacity) //构造指定容量的空栈

{

this.value = newObject[Math.abs(capacity)];

this.top=-1;

}

public SeqStack() //构造默认容量的空栈

{

this(10);

}

public boolean isEmpty() //判断是否空栈，若空栈返回true

{

return this.top==-1;

}

public boolean push(E element) //元素element入栈，若操作成功返回true

{

if (element==null)

return false; //空对象（null）不能入栈

if (this.top==value.length-1) //若栈满，则扩充容量

{

Object[] temp = this.value;

this.value = newObject[temp.length*2];

for (int i=0; itemp.length;i++)

this.value[i] = temp[i];

}

this.top++;

this.value[this.top] = element;

return true;

}

public E pop() //出栈，返回当前栈顶元素，若栈空返回null

{

if (!isEmpty())

return (E)this.value[this.top--];

else

return null;

}

public E get() //取栈顶元素值，未出栈，栈顶元素未改变

{

if (!isEmpty())

return (E)this.value[this.top];

else

return null;

}

public String toString() //返回栈中各元素的字符串描述

{

String str="{";

if (this.top!=-1)

str +=this.value[this.top].toString();

for (int i=this.top-1; i=0; i--)

str += ","+this.value[i].toString();

return str+"} ";

}

实例引用public static void main(String args[])

{

SeqStackString stack = newSeqStackString(20);

System.out.print("Push: ");

char ch='a';

for(int i=0;i5;i++)

{

String str =(char)(ch+i)+"";

stack.push(str);

System.out.print(str+" ");

}

System.out.println("\n"+stack.toString());

System.out.print("Pop : ");

while(!stack.isEmpty()) //全部出栈

System.out.print(stack.pop().toString()+" ");

System.out.println();

}

java编程，设T是存储n个整数的堆。编写程序，完成堆这种数据结构的基本操作，并增加一个操作为：i

public class Test {

private static int a = 1678;

public static void main(String[] args) {

String b = String.valueOf(a);

for(int i=0;ib.length();i++){

System.out.println(b.charAt(i));

}

}

}
