The command-line tool find is used in Unix-like and some other operating systems to identify files based on user-specified criteria and either prints the pathname of each found object or, if some action is required, executes that action on each matched object.
The "find" command has three associated attributes: [path]: This specifies the directory from which to start a search. [options]: It outlines the filtering criteria, such as looking for a file or folder by name, permission, time, or date. [expression]:
Since the word is BOD, likely words that start with BOD will show up.

Software redundancy techniques
When a software system provides the same functionality through the execution of distinct pieces, it is redundant.
What is redundancy?Redundancy has two functions: passive redundancy and active redundancy. Both features use excess capacity to avoid performance decreases from exceeding specification limitations without requiring human involvement. Excess capacity is used in passive redundancy to mitigate the impact of component failures.
Many software engineering techniques have made extensive use of redundancy, such as fault-tolerance and reliability engineering, as well as self-adaptive and self-healing programs.

Phonological memory is the capacity to retain knowledge based on speech in short-term memory. When reading and spelling, we place a lot of reliance on our phonological memory.

counter = 1
for i in range(1, 100) :
counter = counter + 1
print(counter)
Why is the answer 100 not 101
Answer:
The answer is 100 because the range() function in the for loop is set to go from 1 to 100, not 1 to 101. The range() function is inclusive of the start value and exclusive of the end value, so in this case it will only go up to 99, not 100. Additionally, the counter variable is not being incremented correctly within the for loop. The correct syntax for incrementing a counter variable would be "counter += 1" instead of "counter = counter + 1".

Education (Matric, FSc, BS, MS, PhD)
Pay scale (number)
NIC (String)
Functionalities:
SetEmpInformation
UpdateEmpInformation
DeleteEmpInformation
Search and View Emp record by
Emp ID
Employee Name
Age
Job Catagory
Client class should have main function where it may have capacity of maximum 50 Employee records and You are only allowed to use arrays(list is not allowed).
User should be given choice whether to
Add New Employee record
Update Employee Information
Delete Employee Record
Search & view Employee
BY Emp ID
By Employee Name
By Age
By Job Catagory
Choices may be taken by using Input Message dialogs.
When user selects Add New Employee record, It must be kept in mind that no Teacher can have education lower than MS while No Officer can have lower than BS, No Staff can be lesser education than FSc and Labour should be with at least Matric Education. In the same manner for the Teacher pay scale can not be lesser than 18 while for the officer it cant be lesser than 17, the staff should be in between 11 and 16 and the pay scale for labour will be in between 1 and 10.
On update Employee Information, only education payscale and Job category can be updated.
When program is closed all the records should be saved into the file named as EmpDB.dat. all the objects must be serialized into the file. When the program starts if file EmpDB.dat is already present then user should have all required choices to apply on records available in file.
You will use java serialization to implement object serialization.
Note: Inputs should be taken by using Input dialogs and View should be by using showMessageDialog.
Emp ID should be unique and should not be set by user. It should be automatically assigned and Emp ID should start from 9000.
Using knowledge in computational language in JAVA it is possible to write a code that build a program which should have two classes Employee and Client.
Writting the code:public class Employee ffffff
{
private String firstName; // instance variable that stores the first name
private String lastName; // instance variable that stores the last name
private double monthlySalary; // instance variable
// constructor initializes firstName, lastName and monthlySalary with String and double supplied as argument
public Employee (String fname, String lname, double msalary)
{
firstName = fname; // initialize firstName
lastName = lname; // initialize lastName
monthlySalary = msalary; // initialize monthlySalary
// if the monthly salary is not positive, set it to 0.0.
if (msalary < 0.0)
monthlySalary = 0.0;
} // end constructor
// method to set the first name
public void setFirstName (String fname)
{
firstName = fname; // store the first name
} // end method setFirstName
// method to retrieve first name
public String getFirstName ()
{
return firstName;
} // end method getFirstName
// method to set the last name
public void setLastName (String lname)
{
lastName = lname; // store the last name
} // end method setLastName
// method to retrieve last name
public String getLastName ()
{
return lastName;
} // end method getLastName
// method to set the monthly salary
public void setMonthlySalary (double msalary)
{
monthlySalary = msalary; // store the monthly salary
} // end method setMonthlySalary
// method to retrieve monthly salary
public double getMonthlySalary ()
{
return monthlySalary;
} // end method getMonthlySalary
// method to retrieve yearly salary
public double getYearlySalary()
{
double yearlySalary = monthlySalary * 12;
return yearlySalary;
} // end method getYearlySalary
// method to retrieve yearly salary after giving 10% raise
public double getRaiseSalary()
{
double raise = monthlySalary * 0.1 ;
double raiseSalary = ( monthlySalary + raise ) * 12;
return raiseSalary;
} // end method getRaiseSalary
} // end class Employee
