Syntax:

public Object[] getSigners()

Parameter: This method does not accept any paramter.

Return Value: This method returns the signers of this class. If this object represents a primitive type or void, then this method returns null.

Below programs demonstrate the getSigners() method.



Example 1:




// Java program to demonstrate getSigners() method
  
import java.util.*;
  
public class Test {
    public static void main(String[] args)
        throws ClassNotFoundException
    {
  
        // returns the Class object for this class
        Class myClass = Class.forName("Test");
  
        System.out.println("Class represented by myClass: "
                           + myClass.toString());
  
        // Get the signers of myClass
        // using getSigners() method
        System.out.println(
            "Signers of myClass: "
            + Arrays.toString(
                  myClass.getSigners()));
    }
}
Output:
Class represented by myClass: class Test
Signers of myClass: null

Example 2:




// Java program to demonstrate getSigners() method
  
import java.util.*;
  
public class Test {
  
    public static void main(String[] args)
        throws ClassNotFoundException
    {
        // returns the Class object
        Class myClass = Class.forName("java.lang.Integer");
  
        // Get the signers of myClass
        // using getSigners() method
        System.out.println(
            "Signers of myClass: "
            + Arrays.toString(
                  myClass.getSigners()));
    }
}
Output:
Signers of myClass: null
