Class getSigners() method in Java with Examples

Last Updated : 08 Sep, 2021

The getSigners() method of java.lang.Class class is used to get the signers of this class. The method returns the signers of this class. If this object represents a primitive type or void, then this method returns null.

Syntax:

public Object[] getSigners()

Parameter: This method does not accept any parameter.
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

// 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

// 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()));
    }
}
