We can get both union and intersection with two for loops:
String arr1[]= {"java","interview","questions","for","experienced"};
String arr2[]= {"java","fresher","interview","questions"};

Set set=new HashSet();
for(int i=0;i

Why did stop uploading new videos since one year. Please upload other product based companies java interview

[@ramanareddysagili3626]

Immediate question what is the time complexity from interviewer 😮

[@Amarsri19]

String[] s1 = {"java","python","aws"};
String[] s2 = {"java","perl","aws"};
Arrays.stream(s2)
.filter(Arrays.asList(s1)::contains)
.forEach(str -> System.out.print(str + " "));
output: java aws

[@SahanasAllinOneChannel]

String[] s1 = {"java","python","aws"};
String[] s2 = {"java","perl","aws"};

for(String s:Arrays.asList(s1)) {
if(Arrays.asList(s2).contains(s)) {
System.out.println(s);
}
}

[@janagamasainath]

using java 8 one way to find the common String
String[] a = {"java","python","hibernate", "spring"};
String[] b= {"core","java","spring","microservices"};
List a1 = Arrays.asList(a);
List b1 = Arrays.asList(b);
List collect = a1.stream().filter(b1::contains).collect(Collectors.toList());
System.out.println(collect);

Alternate way using java 8:
String[] fruit1 = {"apple", "mango", "banana", "papaya", "apple", "mango", "banana"};

String[] fruit2 = {"apple", "grape", "banana", "orange"};

Stream f1 = Arrays.stream(fruit1);
Stream f2 = Arrays.stream(fruit2);


Map groupString = list.stream().collect(Collectors.groupingBy(Function.identity(), Collectors.counting()));
groupString .entrySet().stream().filter(e -> e.getValue()>1).map(e -> e.getKey()).forEach(System.out::println);
