Code a new method to be exported from ArrayStringLog called howMany() , with the following signature:

public int howMany (String element)

The method returns a integer value indicating how many times element occurs in the log

****Here is the ArrayStringLog:

public class ArrayStringLog implements StringLogInterface

{

protected String name; // name of this StringLog

protected String[] log; // array that holds strings

protected int lastIndex = -1; // index of last string in array

public ArrayStringLog(String name, int maxSize)

// Precondition: maxSize > 0

//

// Instantiates and returns a reference to an empty ArrayStringLog

// object with name "name" and room for maxSize strings.

{

log = new String[maxSize];

this.name = name;

}

public ArrayStringLog(String name)

// Instantiates and returns a reference to an empty ArrayStringLog

// object with name "name" and room for 100 strings.

{

log = new String[100];

this.name = name;

}

public void insert(String element)

// Precondition: This StringLog is not full.

//

// Places element into this StringLog.

{

lastIndex++;

log[lastIndex] = element;

}

public boolean isFull()

// Returns true if this StringLog is full, otherwise returns false.

{

if (lastIndex == (log.length - 1))

return true;

else

return false;

}

public int size()

// Returns the number of Strings in this StringLog.

{

return (lastIndex + 1);

}

public boolean contains(String element)

// Returns true if element is in this StringLog,

// otherwise returns false.

// Ignores case differences when doing string comparison.

{

int location = 0;

while (location <= lastIndex)

{

if (element.equalsIgnoreCase(log[location])) // if they match

return true;

else

location++;

}

return false;

}
