Call 7z to extract the files (including folders) in the compressed package

Because we cannot directly replace the files in a certain folder in the compressed package, we need to extract them first.

Import part:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

Code:

        public static void extractFileOnArchiveByCall7z() {         String filePathStr = "testUpdateZipFile"; // The extracted file name         String zipToolPath = "D:\\7-Zip\\7z.exe"; // 7z tool path         String sourceFilePath = "E:\ \Test_JAVAProgram\\test7z\\testUpdateZipFile.zip"; // Compressed package, there are many types of compressed package supported, I have only tried zip at present, ear         String outputFilePath = "E:\\Test_JAVAProgram\\test7z"; // Extract the path where the file is placed         String cmd = zipToolPath + "" + "x" + "" + sourceFilePath + "" + "-o" + outputFilePath + "" + filePathStr + "" + "-y";         System.out. println(cmd);         InputStream is = null;         InputStreamReader isr = null;         BufferedReader br = null;         try {










            Process process = Runtime.getRuntime().exec(cmd);
            is = process.getInputStream();
            isr = new InputStreamReader(is);
            br = new BufferedReader(isr);
            String line = null;
            while((line = br.readLine()) != null) {
                System.out.println(line);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }finally {
            if(br != null) {
                try {
                    br.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            if(isr != null) {
                try {
                    isr.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            if(is != null) {
                try {
                    is.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
