Below programs illustrates the use of getEntry() function
Example 1: Create a file named zip_file and get the zip file entry using getEntry() function. “file.zip” is a zip file present in f: directory.
// Java program to demonstrate the// use of getEntry() function import java.util.zip.*;import java.util.Enumeration; public class solution { public static void main(String args[]) { try { // Create a Zip File ZipFile zip_file = new ZipFile("f:\\file.zip"); // get the Zip Entry using // the getEntry() function ZipEntry entry = zip_file.getEntry("file1.cpp"); // display the Zip Entry System.out.println("Name: " + entry.getName()); } catch (Exception e) { System.out.println(e.getMessage()); } }} |
Output:
Name: file1.cpp
Example 2: Create a file named zip_file and get the zip file entry using getEntry() function. “file.zip” is a zip file present in f: directory whereas “file4.cpp” is not present in the zip file.
// Java program to demonstrate the// use of getEntry() function import java.util.zip.*;import java.util.Enumeration; public class solution { public static void main(String args[]) { try { // Create a Zip File ZipFile zip_file = new ZipFile("f:\\file.zip"); // get the Zip Entry using // the getEntry() function ZipEntry entry = zip_file.getEntry("file4.cpp"); // display the Zip Entry System.out.println("Name: " + entry.getName()); } catch (Exception e) { System.out.println(e.getMessage()); } }} |
Output:
null
