java.security.DigestOutputStream类的toString()方法用于以字符串格式提供DigestOutputStream的对象。
用法:
public String toString()
返回值:此方法以字符串格式返回DigestOutputStream的对象。
注意:由于不存在“名称”文件,因此本文中的所有程序都无法在在线IDE上运行。您可以在系统上的Java编译器上检查此代码。要检查此代码,请在系统上创建一个文件“名称”。
下面是说明toString()方法的示例:
示例1:
// Java program to demonstrate
// toString() method
import java.security.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
// creating the object of MessageDigest
// and getting instance
// By usng getInstance() method
MessageDigest sr
= MessageDigest.getInstance("MD5");
// creating and intializing
// object of OutputStream
OutputStream is
= new FileOutputStream(
"f:/java/name.txt");
// creating and intializing
// object of DigestOutputStream
DigestOutputStream di
= new DigestOutputStream(is, sr);
// getting the string
// representation of DigestOutputStream
// using toString() method
String str = di.toString();
// display the result
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);
}
}
}
输出:
Status : [Digest Output Stream] MD5 Message Digest from SUN,
示例2:
// Java program to demonstrate
// toString() method
import java.security.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
// creating the object of MessageDigest
// and getting instance
// By usng getInstance() method
MessageDigest sr
= MessageDigest.getInstance("SHA-1");
// creating and intializing
// object of OutputStream
OutputStream is
= new FileOutputStream(
"f:/java/name.txt");
// creating and intializing
// object of DigestOutputStream
DigestOutputStream di
= new DigestOutputStream(is, sr);
// getting the string representation
// of DigestOutputStream
// using toString() method
String str = di.toString();
// display the result
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);
}
}
}
输出:
Status : [Digest Output Stream] SHA-1 Message Digest from SUN,
