java.security.AlgorithmParameterGenerator類的getAlgorithm()方法用於返回與此參數生成器關聯的算法的標準名稱。
用法:
public final String getAlgorithm()
返回值:此方法返回算法的字符串名稱。
下麵是說明getAlgorithm()方法的示例:
示例1:對於算法DSA
// Java program to demonstrate
// getAlgorithm() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
// creating the object of
// AlgorithmParameterGenerator
// and getting instance
// using getInstance() method
AlgorithmParameterGenerator
sr
= AlgorithmParameterGenerator
.getInstance("DSA");
// initializing the AlgorithmParameterGenerator
// with 1024 using initialize() method
sr.init(1024);
// genrating the Parameters
// using getAlgorithm() method
String algo = sr.getAlgorithm();
// printing the string algo
System.out.println("Algorithm : " + algo);
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown : " + e);
}
catch (ProviderException e) {
System.out.println("Exception thrown : " + e);
}
}
}
輸出:
Algorithm : DSA
示例2:對於算法DiffieHellman
// Java program to demonstrate
// getAlgorithm() method
import java.security.*;
import java.util.*;
public class GFG1 {
public static void main(String[] argv)
{
try {
// creating the object of
// AlgorithmParameterGenerator
// and getting instance
// using getInstance() method
AlgorithmParameterGenerator
sr
= AlgorithmParameterGenerator
.getInstance("DiffieHellman");
// initializing the AlgorithmParameterGenerator
// with 1024 using initialize() method
sr.init(1024);
// genrating the Parameters
// using getAlgorithm() method
String algo = sr.getAlgorithm();
// printing the string algo
System.out.println("Algorithm : " + algo);
}
catch (NoSuchAlgorithmException e) {
System.out.println("Exception thrown : " + e);
}
catch (ProviderException e) {
System.out.println("Exception thrown : " + e);
}
}
}
輸出:
Algorithm : DiffieHellman
