Questions

1. This code uses Java 8 Streams to filter employees with salary greater than 4000 using filter() and collects the result into a list using collect(), which is then printed. package com.ruse;

public class Employee { private int id; private String name; private int sal;

Employee (int id,String name,int sal){
    this.id=id;
    this.name=name;
    this.sal=sal;
}

public int getId(){
    return id;
}
public String getName(){
    return name;
}
public int getSal(){
    return sal;
}

} 1 .Q.emloyes Sal >4000 package com.ruse; import org.springframework.boot.SpringApplication; import java.util.Arrays; import java.util.List; import java.util.stream.Collectors; public class AsHardAsYouBreath { public static void main(String[] args) { List employeeList= Arrays.asList(new Employee(1,"bha",25000145), new Employee(2,"bhanga",2546847)); //sal grater tan 4000 List collect = employeeList.stream().filter(e -> e.getSal() > 4000).collect(Collectors.toList()); for (Employee emp:collect){ System.out.println( " id "+ emp.getId()); System.out.println(" name "+emp.getName()); System.out.println(" sal "+emp.getSal()); } }

2. Employee name Start wiith Letter " m" .

public class AsHardAsYouBreath { 
public static void main(String[] args) {
List<Employee> employeeList= Arrays.asList(new Employee(1,"bha",25000145),
            new Employee(2,"bhanga",2546847),
            new Employee(3,"mahan",10000000));
                //Employee nme Strt wwiith " m"
    List<Employee> collect = employeeList.stream().filter(e -> e.getName().startsWith("m") ).collect(Collectors.toList());
    for (Employee emp:collect){
        System.out.println( "   id      "+ emp.getId());
        System.out.println("    name    "+emp.getName());
        System.out.println("    sal     "+emp.getSal());
    } } } }
    
    
  3.  Group the Object(Employee)based on the sal
  
 public class AsHardAsYouBreath {
public static void main(String[] args) { 
List<Employee> data= Arrays.asList(new Employee(1,"bha",25000145),
                                    new Employee(2,"bhanga",2546847),
                                    new Employee(3,"mahan",10000000));

    //group the Object(Employee)based on the sal
    Map<Integer,List<Employee>> collect=data.stream().collect(Collectors.groupingBy(e-> e.getSal()));
     System.out.println(collect); 
// Group employees based on salary
Map<Integer, List<Employee>> groupedBySal = data.stream()
        .collect(Collectors.groupingBy(Employee::getSal)); 
        
        groupedBySal.forEach((salary, empList) -> {
    System.out.println("Salary: " + salary);
    empList.forEach(emp ->
            System.out.println("   ID: " + emp.getId() + ", Name: " + emp.getName())
    );
    System.out.println();   });

} }

4. Second max salary sal

public class AsHardAsYouBreath { public static void main(String[] args) { List emps= Arrays.asList(new Employee(1,"bha",1), new Employee(2,"bhanga",2), new Employee(3,"mahan", 3), new Employee(3,"foura", 4), new Employee(3,"bherra", 5)); //Second m salary sal OptionalInt first = emps.stream().mapToInt(e -> e.getSal()).distinct().sorted().skip(emps.size() - 2).findFirst() ; System.out.println(first.isPresent() ); System.out.println("Second high salary sal "+first.getAsInt()); } }

5.second low salary

public class AsHardAsYouBreath { public static void main(String[] args) { List emps= Arrays.asList(new Employee(1,"bha",1), new Employee(2,"bhanga",2), new Employee(3,"mahan", 3), new Employee(4,"foura", 4), new Employee(5,"bherra", 5)); //second low salary int n=emps.stream().mapToInt(e->e.getSal()).distinct().sorted().skip(1).findFirst().getAsInt(); System.out.println(n); } }

6. To get employees details by their salary salary

public class AsHardAsYouBreath { public static void main(String[] args) {

    List<Employee> emps= Arrays.asList(new Employee(1,"bha",500000000),
            new Employee(2,"bhanga",30000000),
            new Employee(3,"mahan", 200000000),
            new Employee(4,"foura", 100000000),
            new Employee(5,"bherra", 100000000));

    //To get employees details  by their salary salary
    List<Employee> emp= emps.stream().filter(e->e.getSal()==100000000).collect(Collectors.toList());
    for (Employee g:emp) {
        System.out.println(g.getId()+"_____ "+g.getName()+ "______"+ g.getSal() );
    }  }); } }

7.To get employees salary >50000 public class AsHardAsYouBreath { public static void main(String[] args) { List emps= Arrays.asList(new Employee(1,"bha",500000000), new Employee(2,"bhanga",30000000), new Employee(3,"mahan", 200000000), new Employee(4,"foura", 100000000), new Employee(5,"bherra", 100000000)); //To get employees salary >50000 List emp = emps.stream().filter(e->e.getSal()>50000).collect(Collectors.toList()); for (Employee em:emp ) { System.out.println(em.getId()+" "+em.getName()+ " "+ em.getSal() ); } } }
