I have a scenario to read zip files from a server URL. But I get a Java heap error when i append the string in the stringbuilder
public static void main(String args[]) {
String url = "https://server/test.zip";
LOG.info("Url {}", url);
String content = readZipFileFromRemote(url);
System.out.println(content);
}
private static String readZipFileFromRemote(String remoteFileUrl) {
StringBuilder sb = new StringBuilder();
try {
URL url = new URL(remoteFileUrl);
InputStream in = new BufferedInputStream(url.openStream(), 1024);
ZipInputStream stream = new ZipInputStream(in);
byte[] buffer = new byte[1024];
ZipEntry entry;
while ((entry = stream.getNextEntry()) != null) {
int read;
while ((read = stream.read(buffer, 0, 1024)) >= 0) {
sb.append(new String(buffer, 0, read));
}
}
} catch (Exception e) {
e.printStackTrace();
}
return sb.toString();
}
Error
java.lang.OutOfMemoryError: Java heap space

Can someone help me with this?
