Reading a file and put it in a String

Question

I have a file and I want to put its rows in an array of strings
I've done that
File file = new File("./arguments/tabsArguments.txt");
FileReader fileReader = new FileReader(file);
String mystring;
fileReader.read(mystring,0,20);
for (int i=0;i<i_string.length();i++)
tabs=i_string;
fileReader.read(mystring,0,20);
It throws this exception
java.io.StreamCorruptedException: invalid stream header.
I've done by myself the file "tabsArguments.txt"
and it's a simple list of string.help please!

Answer 1

Nothing in the code you posted can cause StreamCorruptedException to be thrown. Also, the code fragment you posted can't even be compiled because mystring is used before initialization, FileReader doesn't have a method with the signature read(String, int, int), and variable "tabs" is not defined. StreamCorruptedException is thrown "when control information that was read from an object stream violates internal consistency checks." This suggests that you use ObjectInputStream somewhere but I can't see where. http://java.sun.com/j2se/1.4.1/docs/api/java/io/StreamCorruptedException.html
so from now on please post the actual code you have problems with...
