Java ZipEntry getMethod() function with examples
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
import java.util.zip.*;
import java.util.Enumeration;
import java.util.*;
import java.io.*;
public class solution {
public static void main(String args[])
{
try {
ZipFile zip_file = new ZipFile( "f:\\file1.zip" );
ZipEntry entry = zip_file.getEntry( "file.zip" );
int input = entry.getMethod();
System.out.println( "compression method : " + input);
}
catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
|
Output:
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
import java.util.zip.*;
import java.util.Enumeration;
import java.util.*;
import java.io.*;
public class solution {
public static void main(String args[])
{
try {
ZipFile zip_file = new ZipFile( "f:\\file1.zip" );
ZipEntry entry = zip_file.getEntry( "file1.cpp" );
int input = entry.getMethod();
System.out.println( "compression method : " + input);
}
catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
|
Output:
compression method : 8
