Question

Your second task is to create a method called VerifyCredentials and return a Boolean variable verified. The method verify credentials will receive a username and password and will ask a user to input her password. The user has only three chances to input a wrong password until her account is locked. If the password is correct, the method should print "Correct password" and assign the value true to the variable verified. If the password is incorrect the third time, the system should print "Incorrect password, locked account" and assign the value false to the variable verified. Write the pseudocode for the method VerifyCredentials. Write the jave code for the method VerifyCredentials. Assume the method receives the username with value "mary" and password "503". Trace how your method would work for the inputs: "hi" and "hellow".
