content of
myproperty.properties file

directory = c:\ddd\
subdirectories = df,d,g

how do i read the file displaying whole directory
Properties property = new Properties();
FileInputStream inputFile = null;
try{

i am trying to create a function that takes as an input a file directory
c:\aaaa\bbb\cc. i pass it as string. - is this right aproach
but then i need to get to the last folder cc and it content put into
an array (cc - containts somr sub folders) Is using tokens to split the the string s right way.
public void func(String s)
{

}


thank you for help

would that be more appropriate

private int arr[];

public void setArr(int bArr[])
{
for (int i=0; i<aArr.length-1; i++)
arr[i] = aArr[i];
}

public int[] getArr()
{
if (arr==null)
arr=new int[10];
return arr;
}


thanks for help

hi
1.
i have
public static final int BOX = 0;
public static final int CIRCLE = 1;
if i want to put the elements into an array do the array have to be
public static final
or it can be private
and then i just write set and get methods to access and update array


2. is it how I use get and set methods?
private StringBuffer m[][];

// set methods
public void setm(int a[][])
{
m = a;
}
public int[][] getm()
{
return m;
}

any help appreciated
thanks
