Question
Ask the user to enter the name of an employee and check if the person exists in the array list, the search must be case insensitive. Display the message “EMPLOYEE found”, if the name is found in the list and display the employee’s corresponding employee information (name, hours, rate, and pay). Otherwise, display “EMPLOYEE NOT found”. EMPLOYEE is the name of the person. So, if the input for name is LILY TAYE, we’ll display something like LILY TAYE, 10 20 200. If the input for name is keke mamo , we’ll display something like keke mamo NOT found, if we don’t have an employee named keke mamo, in java.
Explanation / Answer
Please find the code as shown below
public class Employee
{
private String name;
private Double hours;
private Double rate;
private Double pay;
public Employee (String name, Double hours, Double rate, Double pay)
{
this. name = name;
this. hours = hours;
this.rate = rate;
this.pay = pay;
}
public String toString()
{
return "Employee[name = " + name + ", hours = " + hours + ", rate = " + rate ", pay = " + pay + "]";
}
public String getName()
{
return name;
}
public Double getHours()
{
return hours;
}
public Double getPay(){
return pay;
}
public Double getRate(){
return rate
}
public void setName(Double name)
{
this.name = name;
}
public void setHours(Double hours)
{
this. hours = hours;
}
public void setPay(Double pay)
{
this.pay = pay;
}
public void setRate(Double rate)
{
this. rate = rate;
}
