Java collections can store arrays of strings

• Use ArrayList or HashSet to store arrays of strings

• ArrayList allows duplicates while HashSet does not

• Example: ArrayList names = new ArrayList<>();

• Example: H...read more

package com.java;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.HashSet;

import java.util.List;

import java.util.Map;

import java.util.Set;

public class String_Collection {

public static void main(String[] args) {

// List example

List<String> stringList = new ArrayList<>();

stringList.add("apple");

stringList.add("banana");

stringList.add("orange");

System.out.println("List Example:");

for (String fruit : stringList) {

System.out.println(fruit);

}

// Set example

Set<String> stringSet = new HashSet<>();

stringSet.add("apple");

stringSet.add("banana");

stringSet.add("orange");

System.out.println("\nSet Example:");

for (String fruit : stringSet) {

System.out.println(fruit);

}

// Map example

Map<Integer, String> stringMap = new HashMap<>();

stringMap.put(1, "apple");

stringMap.put(2, "banana");

stringMap.put(3, "orange");

System.out.println("\nMap Example:");

for (Map.Entry<Integer, String> entry : stringMap.entrySet()) {

System.out.println(entry.getKey() + ": " + entry.getValue());

}

}

}

In this example, we've used three different Java collections: ArrayList (for a list of strings), HashSet (for a set of strings), and HashMap (for a map with integer keys and string values). The program adds strings to each collection and then demonstrates iterating through and printing the elements
