The getMethod() function is a part of java.util.zip package. The function returns the compression method of a specific ZipEntry passed as parameter or -1 if not specified.
Function Signature :
public int getMethod()
Syntax :
zip_entry.getMethod();
Parameters :No parameter is required for this function.
Return value :The function returns a int value, the compression method of this ZipEntry or -1 if not specified.
Exceptions :The function does not throw any exception.
Below programs illustrates the use of getMethod() function
Example 1: We will create a file named zip_file and get the zip file entry using getEntry() function and then get the compression method of the specified ZipEntry.”file.zip” is a zip file present in f: directory. we will take a “.zip” file as ZipEntry
// Java program to demonstrate the// use of getMethod() function import java.util.zip.*;import java.util.Enumeration;import java.util.*;import java.io.*; public class solution { public static void main(String args[]) { try { // Create a Zip File ZipFile zip_file = new ZipFile("f:\\file1.zip"); // get the Zip Entry using // the getEntry() function ZipEntry entry = zip_file.getEntry("file.zip"); // Get the compression method // using the getMethod() // function int input = entry.getMethod(); // Display the compression method System.out.println("compression method : " + input); } catch (Exception e) { System.out.println(e.getMessage()); } }} |
compression method : 8
Example 2: We will create a file named zip_file and get the zip file entry using getEntry() function and then get the compression method of the specified ZipEntry.”file.zip” is a zip file present in f: directory. we will take a “.cpp” file as ZipEntry
// Java program to demonstrate the// use of getMethod() function import java.util.zip.*;import java.util.Enumeration;import java.util.*;import java.io.*; public class solution { public static void main(String args[]) { try { // Create a Zip File ZipFile zip_file = new ZipFile("f:\\file1.zip"); // get the Zip Entry using // the getEntry() function ZipEntry entry = zip_file.getEntry("file1.cpp"); // Get the compression method // using the getMethod() // function int input = entry.getMethod(); // Display the compression method System.out.println("compression method : " + input); } catch (Exception e) { System.out.println(e.getMessage()); } }} |
compression method : 8
