The getTotalIn() function of the Deflater class in java.util.zip returns the total number of uncompressed bytes input provided till now.
Function Signature:
public int getTotalIn()
Syntax:
d.getTotalIn();
Parameter: The function requires no parameter
Return Type: The function returns an int value which is the total number of uncompressed bytes input.
Exception: The function does not throw any exception
Example 1:
// Java program to describe the use // of getTotalIn() function import java.util.zip.*;
import java.io.UnsupportedEncodingException;
class GFG {
public static void main(String args[])
throws UnsupportedEncodingException
{
// deflater
Deflater d = new Deflater();
// get the text
String pattern = "GeeksforGeeks" , text = "" ;
// generate the text
for ( int i = 0 ; i < 4 ; i++)
text += pattern;
// set the input for deflator
d.setInput(text.getBytes( "UTF-8" ));
// finish
d.finish();
// output bytes
byte output[] = new byte [ 1024 ];
// compress the data
int size = d.deflate(output);
// compressed String
System.out.println( "Compressed String :"
+ new String(output)
+ "\n Size " + size);
// original String
System.out.println( "Original String :"
+ text + "\n Size "
+ text.length());
// get the total number of uncompressed
// bytes input so far
System.out.println( "Total Input value :"
+ d.getTotalIn());
// end
d.end();
}
} |
Output:
Compressed String :x?sOM?.N?/r???q?? Size 21 Original String :GeeksforGeeksGeeksforGeeksGeeksforGeeksGeeksforGeeks Size 52 Total In value :52
Note: The problem arises when the length of the input is greater than Integer.MAX_VALUE. Then the result may overflow, we should use getBytesRead() function instead
