Hi I need to calculate the Length of a message saved in a text file so
i wrote the following code:
int len;
FileInputStream Message_File=new FileInputStream
BufferedReader buff=new BufferedReader(new
String Input_Message=new String();
System.out.println("Your input message is as following:");
while((Input_Message=buff.readLine() )!=null){
// Calculating the the length of our message in unit of bits

this will only give me the length of the last line in the Mesage not
the length of all the message ,so when I Put this statement after while
loop :
it will give null exeption:
at final_append.CopyBytes.main(
Exception in thread "main"
So what i can do???

Instead of simply assigning the new length to the variable len, you need to accumulate those lengths.

i dont know what kinda of value the variable would be, but you could

set up a variable, which i saw you say byte.

so do this in the while loop..

info += len;

so every time it adds the length of input_w/e to info.

hope this helps a lil


You down with OOP? Yeah you know me!
