String pathArr[] = split(aPath, "/");
String arrFullPath[];

arrFullPath = pathArr;

}
else {
arrFullPath [0] = "/"; ---> getting error here(variable not initialised)
}
return arrFullPath;

}

Hello Piyush,
You are getting error because your initialization of array is actually occurs in the "if" block.

if(pathArr.length > 0){
         arrFullPath = pathArr;
}

<hr></blockquote>
This statement may never be executed. You have to initialize ellements of the array before you can use them.
Hope this will help.

Hi Irene,
Can u suggest modifications to the code.
If the 1st array length is zero then i wanna return "/", if not then whole array.

There are many ways, try this:

private String[] GetFullPath(String aPath) {
String pathArr[] = split(aPath, "/");
String arrFullPath[];
if(pathArr.length > 0){
     arrFullPath = pathArr;
}
else {
     arrFullPath = new String []{"/"};
}
return arrFullPath;
}
