DigestInputStream.toString() method in Java with Examples
The toString() method of java.security.DigestInputStream class provide the object of DigestInputStream in string format.
Syntax:
public String toString()
Return Value: This method returns the object of DigestInputStream in string format.
Note : All the programs in this article won’t run on online IDE as no ‘name’ file exists. You can check this code on Java compiler on your system. To check this code, create a file ‘name’ on your system.
Below are the examples to illustrate the toString() method:
Example 1:
Java
import java.security.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
MessageDigest sr
= MessageDigest.getInstance( "MD5" );
InputStream is
= new FileInputStream( "f:/java/name.txt" );
DigestInputStream di
= new DigestInputStream(is, sr);
String str = di.toString();
System.out.println( "Status : " + str);
}
catch (NoSuchAlgorithmException e) {
System.out.println( "Exception thrown : " + e);
}
catch (NullPointerException e) {
System.out.println( "Exception thrown : " + e);
}
catch (FileNotFoundException e) {
System.out.println( "Exception thrown : " + e);
}
}
}

Output:
Status : [Digest Input Stream] MD5 Message Digest from SUN,
Example 2:
Java
import java.security.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
MessageDigest sr
= MessageDigest.getInstance( "SHA-1" );
InputStream is
= new FileInputStream( "f:/java/name.txt" );
DigestInputStream di
= new DigestInputStream(is, sr);
String str = di.toString();
System.out.println( "Status : " + str);
}
catch (NoSuchAlgorithmException e) {
System.out.println( "Exception thrown : " + e);
}
catch (NullPointerException e) {
System.out.println( "Exception thrown : " + e);
}
catch (FileNotFoundException e) {
System.out.println( "Exception thrown : " + e);
}
}
}

Output:
Status : [Digest Input Stream] SHA-1 Message Digest from SUN,
