Deflater getTotalIn() function in Java with examples
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 = "w3wiki", 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 :w3wikiw3wikiw3wikiw3wiki 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
