如何使用Java将文件从Zip文件读取到内存中？

好吧，只需将将文件写入文件的部分更改为您要处理的数据即可。

while((entry = zis.getNextEntry()) != null) {    System.out.println("Extracting: " + entry);    int count;    byte[] data = new byte[BUFFER];    String filename = entry.getName();    System.out.println("Filename: " + filename);    while ((count = zis.read(data, 0, BUFFER)) != -1) {       // Do whatever you want with the data variable       System.out.println(data);    }}
