Association - Exercise 1

You need to develop an application for cab service providers by implementing the classes based on the class diagram and description given below. Note: Driver class is provided to you. Method Description CabServiceProvider CabServiceProvider(String cabServiceName, int totalCabs) Initialize all the instance variables appropriately with the values passed to the constructor. calculateRewardPrice(Driver driver) Calculate and return the bonus of the driver based on the below table. If averageRating of the driver is less than 4, return the bonus as 0. In case of any invalid value, return the bonus as 0. Note: Round off the bonus to 2 decimal digits. Implement the appropriate getter and setter methods. Perform case-sensitive comparison wherever applicable. Test the functionalities using the provided Tester class. Sample Input and Output Input For CabServiceProvider object cabServiceProvider1 with cabServiceName = Halo and totalCabs = 50 Driver object - driver1 Driver object - driver2 Driver object - driver3 Output,coding savior,infosys assignment quiz and lex genrric ansewer,infosys generic java program, code answer,code saviour,code monk,coding bar,code solution for infosys assignmenet,code saviour trend

String - Exercise 1

String - Exercise 1

Complete the removeWhiteSpaces() method given in the Tester class.

Method Description

removeWhiteSpaces(String str)

Remove all the white spaces from the string passed to the method and return the modified string.

Test the functionalities using the main() method of the Tester class.

Sample Input and Output

class Tester{

public static String removeWhiteSpaces(String str){
String noSpaceStr=str.replaceAll("\\s","");//usingbuiltinmethod
//Implementyourcodehereandchangethereturnvalueaccordingly
return noSpaceStr;
    }
    
    public static void main(String args[]){
        String str = "Hello   How are you   ";
        str = removeWhiteSpaces(str);
        System.out.println(str);
    }
}

Encapsulation - Exercise 1

Problem Statement

Consider the class Employee given below for representing employees of an organization. It has 5 different instance variables and a method to calculate the total salary based on the jobLevel.

Salary is calculated in the calculateSalary() method.

Make necessary changes to the class by making all the attributes private and by adding necessary accessor and mutator methods thus bringing in Encapsulation.

class Employee {

 String employeeId;
 String employeeName;
 int salary;
 int bonus;
int jobLevel;
public String getEmployeeId(){
return employeeId;
}
public void setEmployeeId(String employeeId){
this.employeeId=employeeId;
}
public String getEmployeeName(){
return employeeName;
}
public void setEmployeeName(String employeeName){
this.employeeName=employeeName;
}
public int getSalary(){
return salary;
}
public void setSalary(int salary){
this.salary=salary;
}
public int getBonus(){
return bonus;
}
public void setBonus(int bonus){
this.bonus=bonus;
}
public int getJobLevel(){
return jobLevel;
}
public void setJobLevel(int jobLevel){
this.jobLevel=jobLevel;
}

    public void calculateSalary() {
        if (this.jobLevel >= 4) {
            this.bonus = 100;
        } else {
            this.bonus = 50;
        }
        this.salary += this.bonus;
    }
}

class Tester {

    public static void main(String args[]) {

        Employee employee = new Employee();
        employee.employeeId = "C101";
        employee.employeeName = "Steve";
        employee.salary = 650;
        employee.jobLevel = 4;

        employee.calculateSalary();

        System.out.println("Employee Details");
        System.out.println("Employee Id: " + employee.employeeId);
        System.out.println("Employee Name: " + employee.employeeName);
        System.out.println("Salary: " + employee.salary);

    }

selection Control Structure - Assignment 4

Selection Control Structure - Assignment 4

Implement a program to calculate the product of three positive integer values. However, if one of the integers is 7, consider only the values to the right of 7 for calculation. If 7 is the last integer, then display -1.

Note: Only one of the three values can be 7.

Sample Input and Output

class Tester{
public static void main(String[]args){
int a=2,b=6,c=7;
int x=0;
if(a==7)
{
x=b*c;
}
else if(b==7)
{
x=c;
}
else if(c==7)
{
x=-1;
}
else
{
x=a*b*c;
}
System.out.println(x);
}
}
