SecurityManager Class getSecurityContext() method

  • getSecurityContext() method is available in java.lang package.
  • getSecurityContext() method is used to return an object that encapsulates or binds the current execution environment and we don't override this method so it returns an object of "AccessControlContext".
  • getSecurityContext() method is required to determine whether the untrusted method is eligible to execute on its own or not.
  • getSecurityContext() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • getSecurityContext() method does not throw an exception at the time returning an object of executing the environment.

Syntax:

    public Object getSecurityContext();

Parameter(s):

  • It does not accept any parameter.

Return value:

The return type of this method is Object, it returns an object that encapsulates enough information of an environment executing currently to operate some security validations.

Example:

// Java program to demonstrate the example 
// of Object getSecurityContext() method of
// SecurityManager 

import java.security.*;

public class GetSecurityContext {
    public static void main(String[] args) {
        // By using setProperty() method is to set the policy property 
        // with security manager

        System.setProperty("java.security.policy", "file:/C:/java.policy");

        // Instantiating a SecurityManager object
        SecurityManager smgr = new SecurityManager();

        // By using setSecurityManager() method is to set the
        // security manager
        System.setSecurityManager(smgr);

        // By using getSecurityContext() method is to return the
        // object of security context
        Object ob = smgr.getSecurityContext();
