Infosys Java8 Coding Interview Question Answers

Like these questions are asking for interview of java developer with 2years experience sir? Is it for Sure sir?? Im preparing now thats why asked !

Thanks a lot

thank u so much brother

Hi @CloudTech

One more way


import java.util.*;
import java.util.stream.*;

public class MyClass {
public static void main(String args[]) {
List<Integer> intList = Arrays.asList(10,6,2,6,4,8);
int totalSum = intList.stream().mapToInt(Integer::intValue).sum();
int towDivisibleSum = intList.stream().filter(p -> p % 2 == 0).reduce(Integer::sum).orElse(0);

if(totalSum == towDivisibleSum)
System.out.println("All the numbers are divisible by 2");
else
System.out.println("All the numbers are NOT divisible by 2");

}
}

Hi @CloudTech,
The other way is given below


import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;
public class MyClass {
public static void main(String args[]) {
List<Integer> intList = Arrays.asList(2,2,8,6,4,10,890,90004,890000063);
long divTwoList = intList.stream().filter(p-> p % 2 == 0).count();
if(divTwoList == intList.size())
System.out.println("All numbers in the given list are divisible by 2");
else
System.out.println("All numbers in the given list are NOT divisible by 2");
}
}

without using streams how to do?

can u please also provide interview questions?

are these recent interviews?

Great Thanks.

That helps a lot.
Thanks a zillion.
The other way to get the desired output is

import java.util.*;
import java.util.stream.*;
import java.util.function.*;

public class MyClass {
public static void main(String args[]) {
List<Integer> intList = Arrays.asList(2,4,6,8);
Long totalNum = intList.stream().collect(
Collectors.filtering(x-> x % 2 == 0,
Collectors.counting()
)
);

if(totalNum == intList.size())
System.out.println("All the numbers are divisible by 2");
else
System.out.println("All the numbers are not divisible by 2");

}
}
