Java program to convert a Set to an array
The Set object provides a method known as toArray(). This method accepts an empty array as argument, converts the current Set to an array and places in the given array. To convert a Set object to an array −
- Create a Set object.
- Add elements to it.
- Create an empty array with size of the created Set.
- Convert the Set to an array using the toArray() method, bypassing the above-created array as an argument to it.
- Print the contents of the array.
Example
import java.util.HashSet;
import java.util.Set;
public class SetToArray {
public static void main(String args[]){
Set<String> set = new HashSet<String>();
set.add("Apple");
set.add("Orange");
set.add("Banana");
System.out.println("Contents of Set ::"+set);
String[] myArray = new String[set.size()];
set.toArray(myArray);
for(int i=0; i<myArray.length; i++){
System.out.println("Element at the index "+(i+1)+" is ::"+myArray[i]);
}
}
}Output
Contents of Set ::[Apple, Orange, Banana] Element at the index 1 is ::Apple Element at the index 2 is ::Orange Element at the index 3 is ::Banana
