下边内容段是关于Java通过gzip对字符串进行压缩和解压缩的内容,希望对小伙伴们也有帮助。
public static String uncompressString(String str) throws IOException {
if (str == null ¦¦ str.length() == 0) {
return str;
}
ByteArrayOutputStream out = new ByteArrayOutputStream();
ByteArrayInputStream in = new ByteArrayInputStream(str
.getBytes("ISO-8859-1"));
GZIPInputStream gunzip = new GZIPInputStream(in);
byte[] buffer = new byte[256];
int n;
while ((n = gunzip.read(buffer)) >= 0) {
out.write(buffer, 0, n);
}
return out.toString();
}
public static void main(String[] args) throws IOException {
String a = compressString("China");
System.out.println(a);
System.out.println(a.length());
String b = uncompressString(a);
System.out.println(b);
}
