The setCompressedSize() function is a part of java.util.zip package. The function sets the compressed size of the Zip Entry to specified long value.
Function Signature :
public void setCompressedSize(long val)
Syntax :
zip_entry.setCompressedSize(val);
Parameters :The function takes a long value as parameter.
Return value :The function does not return any value.
Exceptions :The function does not throw any exception.
Below programs illustrates the use of setCompressedSize() function
Example 1: We will create a file named zip_file and get the zip file entry using getEntry() function and then set the Compressed Size 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 setCompressedSize() 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" ); // set the CompressedSize // using the getCompressedSize() // function entry.setCompressedSize( 123 ); // Get the CompressedSize // using the getCompressedSize() // function long input = entry.getCompressedSize(); // Display the CompressedSize System.out.println( "CompressedSize : " + input); } catch (Exception e) { System.out.println(e.getMessage()); } } } |
CompressedSize : 123
Example 2: We will create a file named zip_file and get the zip file entry using getEntry() function and then set the CompressedSize 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 setCompressedSize() 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" ); // set the CompressedSize // using the getCompressedSize() // function entry.setCompressedSize( 123 ); // Get the CompressedSize // using the getCompressedSize() // function long input = entry.getCompressedSize(); // Display the CompressedSize System.out.println( "CompressedSize : " + input); } catch (Exception e) { System.out.println(e.getMessage()); } } } |
CompressedSize : 123
