为FixedCapacityStackOfStrings添加一个方法isFull()。

FixedCapacityStackOfStrings:

*/
package com.furzoom.lab.algs.ch103;

/**

*
* @version
*/
public class FixedCapacityStackOfStrings
{
private String[] a; // stack entries
private int n;      // size;
public FixedCapacityStackOfStrings(int cap)
{
a = new String[cap];
}

public boolean isEmpty()
{
return n == 0;
}

public int size()
{
return n;
}

public void push(String item)
{
a[n++] = item;
}

public String pop()
{
return a[--n];
}

public boolean isFull()
{
return n == a.length;
}

public static void main(String[] args)
{

}

}


测试:

/**

*/
package com.furzoom.lab.algs.ch103;

import edu.princeton.cs.algs4.StdIn;

/**
* ClassName    : E10301 <br>
* Function     : TODO ADD FUNCTION. <br>
* date         : Sep 28, 2016 11:26:45 AM <br>
*
* @version
*/
public class E10301
{
public static void main(String[] args)
{
FixedCapacityStackOfStrings s;
s = new FixedCapacityStackOfStrings(3);
while (!StdIn.isEmpty())
{
String item = StdIn.readString();
if (s.isFull())
{
System.out.println("Stack is full.");
break;
}
s.push(item);
}
}

}


结果:

>java -cp ".;../lib/algs4.jar" com
.furzoom.lab.algs.ch103.E10301
to
be
or
not
Stack is full.
