write my assignment 22592
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;
}
