Hi,

I run into the following errors when i try to store a large file into a string.

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
    at java.util.Arrays.copyOf(Arrays.java:2882)
    at java.lang.AbstractStringBuilder.expandCapacity(AbstractStringBuilder.java:100)
    at java.lang.AbstractStringBuilder.append(AbstractStringBuilder.java:515)
    at java.lang.StringBuffer.append(StringBuffer.java:306)
    at rdr2str.ReaderToString.main(ReaderToString.java:52)

As is evident, i am running out of heap space. Basically my pgm looks like something like this.

FileReader fr = new FileReader(<filepath>);
sb = new StringBuffer();
char[] b = new char[BLKSIZ];

while ((n = fr.read(b)) > 0) 
     sb.append(b, 0, n);    

fileString = sb.toString();

Can someone suggest me why i am running into heap space error? Thanks.
