Example of DeflaterOutputStream in Java
November 23, 2023
DeflaterOutputStream provides output stream compressing data in DEFLATE format. In our example we have a file and in the file there is some test data. Using DeflaterOutputStream we will compress our test data in DEFLATE format.
Example
DeflaterOutputStreamTest.java
package com.concretepage;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.util.zip.DeflaterOutputStream;
public class DeflaterOutputStreamTest {
public static void main(String[] args) throws Exception {
FileInputStream in = new FileInputStream("D:\\page\\file.txt");
FileOutputStream out = new FileOutputStream("D:\\page\\file_new.dfl");
DeflaterOutputStream dos = new DeflaterOutputStream(out);
int ch=0;
while ((ch = in.read())!=-1){
ch = in.read();
dos.write(ch);
}
dos.close();
in.close();
}
}
DeflaterOutputStream has written this file with the name file_new.dfl. We can find in the specified directory.
