 Java 8 Innards Fresco Play Solution | T Factor 





Solutions:- The Course Id of Java 8 Innards is 55961. It is completely related to new features of java languages. You will learn Stream API, Lambda Expression, Functional Interface, Annotations, etc. 

1. Lambda Expression 

import java.io.*;
import java.util.*;

class Employee
{
    // WRITE CODE OF CONSTRUCTOR 
    
    String name;
    int id;
    int age;
    public Employee(String name,int id,int age){
        this.name = name;
        this.id = id;
        this.age = age;
    }
}

class SortEmployees 
{
    void sortEmployees(ArrayList<Employee> empList) 
    {
        // LAMBDA EXPRESSION CODE
        Collections.sort(empList,(o1,o2) -> o1.name.compareTo(o2.name));
        for(Employee x:empList)
        {
            System.out.println(x.name+" "+x.id+" "+x.age);
        }
        
        
    }
}

public class SortEmployeesMain
{
    public static void main(String[] args) throws Exception
    {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
ArrayList<Employee> empList=new ArrayList<>();
int n=Integer.parseInt(br.readLine().trim());
for(int i=0;i<n;i++)
{
String inp=br.readLine();
         String inparr[]=inp.split(" ");
 
Employee ws=new Employee(inparr[0],Integer.parseInt(inparr[1]), Integer.parseInt(inparr[2]));
empList.add(ws);
}
SortEmployees s1=new SortEmployees();
s1.sortEmployees(empList);
    }
}

2. Java Interface Hands-On (1):- 




import java.io.*;
import java.util.function.Consumer;
import java.util.function.IntPredicate;
import java.util.stream.IntStream;
import java.util.stream.LongStream;
import java.util.function.*;
import java.math.BigInteger;
class PrimeComposite_Factorial
{
    void primeOrComposite(int n)
    {
        //Enter your Code here
        if(n<=1)
            System.out.println("Neither Prime Nor Composite");          
        else{ 
            Predicate<Integer> lesser = (x) -> {
                boolean res = IntStream.rangeClosed(2,x/2).noneMatch(i-> x%i==0);
                return res;
            };
                if(lesser.test(n))
                {
                    Consumer<Integer> lesserthan = (x) -> {
                        System.out.println("Prime");
                    };
                lesserthan.accept(n);    
                }
                else{
                    System.out.println("Composite");
                }
        }
        
    }
    
    void findFactorial(int n)
    {
        //Enter your Code here
        Consumer<Integer> con = (a) -> {
            BigInteger n1 = BigInteger.valueOf(n);
            BigInteger sum = BigInteger.ONE;
            for(BigInteger i = BigInteger.ONE;i.compareTo(n1) <= 0;i=i.add(BigInteger.ONE))                  {
                    sum = sum.multiply(i);
                  }
            System.out.println(sum);
        };
        con.accept(n);
    }
}

public class PrimeComposite_FactorialMain
{
    public static void main(String[] args) throws Exception
{
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
int n=Integer.parseInt(br.readLine().trim());
PrimeComposite_Factorial xyz=new PrimeComposite_Factorial();
 
xyz.primeOrComposite(n);
xyz.findFactorial(n);
}
}

        {
            String rest1[] = str.split(",");
            for(int i=0;i<rest1.length;i++)
            {
                // All should be in lowercase in equal.
                if(rest1[i].equals("cheese sandwich") || rest1[i].equals("corn sandwich")|| rest1[i].equals("mix veg sandwich")){
                    res.add(i,rest1[i]);
                    }
                    else
                    {
                        System.out.println("Incorrect Input");
                        return;
                    }
            }
            res.forEach((x) -> System.out.println(x));
        };
        Supplier<List<String>> Tejatechviews = ()-> res;
        rest.accept(input);
    }
}
