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+"} ";
}
