Following is an example to implement Quintet class from Quartet class in Java −Exampleimport org.javatuples.Quartet; import org.javatuples.Quintet; public class MyDemo { public static void main(String[] args) { Quartetquartet = new Quartet( "Table", "Chair", "Pen", "Paper"); System.out.println("Quartet elements = " + quartet); Quintetquintet = quartet.add("Notebook"); System.out.println("Quintet (implemented from Quartet) elements = " + quintet); } }OutputQuartet elements = [Table, Chair, Pen, Paper] Quintet (implemented from Quartet) elements = [Table, Chair, Pen, Paper, Notebook]Let us now see another example to implement Quintet class from ...

The division operator in Java includes the Division, Modulus, and the Divide And Assignment operator. Let us work with them one by one −Divison OperatorThe division operator divides left-hand operand by right-hand operand.Modulus OperatorThe modulus operator divides left-hand operand by right-hand operand and returns remainder.Divide And Assignment OperatorThis operator divides left operand with the right operand and assign the result to left operand.Let us now see an example −Examplepublic class Demo { public static void main( String args[] ) { int a = 10; int b = 20; int c ...

Following is an example to implement Quartet class from Triplet class in Java −Exampleimport org.javatuples.Triplet; import org.javatuples.Quartet; public class MyDemo { public static void main(String[] args) { Triplettriplet = new Triplet("Gray", "Blue", "Gray100"); System.out.println("Triplet elements = " + triplet); Quartetquartet = triplet.add("Blue30"); System.out.println("Quartet (Implemented from Triplet) = " + quartet); } }OutputTriplet elements = [Gray, Blue, Gray100] Quartet (Implemented from Triplet) = [Gray, Blue, Gray100, Blue30]Let us now see another example to implement Quartet class from Triplet. This inserts element at position 3rd −Exampleimport org.javatuples.Triplet; import ... Read More
The join() method of Ints class returns a string containing the supplied int values separated by separator. The syntax is as follows −public static String join(String separator, int[] arr)Here, separator parameter is something that should appear between consecutive values, whereas arr is an array of int values.Let us first see an example −Exampleimport com.google.common.primitives.Ints; class Demo { public static void main(String[] args) { int[] myArr = { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 }; System.out.println(Ints.join("-", myArr)); int index = Ints.indexOf(myArr, 40); if ...

The indexOf() method of the Ints class returns the index of the first appearance of the value target in array. The syntax is as follows −public static int indexOf(int[] arr, int target)Here, parameter arr is an array of int values and target is the value to be checked for first appearance.Let us now see an example −Exampleimport com.google.common.primitives.Ints; class Demo { public static void main(String[] args) { int[] arr = { 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 }; int index = Ints.indexOf(arr, 40); if (index != ...

Let’s say the following is our stream −Stream stream = Stream.of(50, 100, 200, 400, 800, 1000, 2000);Now, convert stream to an array using toArray() −Object[] objArr = stream.toArray(Object[] ::new);Following is the program to convert Stream to an Array in Java −Exampleimport java.util.*; import java.util.stream.*; import java.util.function.Function; public class Demo { public static void main(String args[]) { Stream stream = Stream.of(50, 100, 200, 400, 800, 1000, 2000); Object[] objArr = stream.toArray(Object[] ::new); System.out.println("Array = "+ Arrays.toString(objArr)); } }OutputArray = [50, 100, 200, 400, 800, 1000, 2000]
Let’s say the following is our Set with string values −Set set = new HashSet(); set.add("Laptop"); set.add("Mobile"); set.add("Tablet"); set.add("LCD"); set.add("LED");Now, let us convert it to List −List list = new ArrayList(set);Following is the program to convert Set to List in Java −Exampleimport java.util.*; import java.util.stream.*; public class Demo { public static void main(String args[]) { Set set = new HashSet(); set.add("Laptop"); set.add("Mobile"); set.add("Tablet"); set.add("LCD"); set.add("LED"); set.add("Desktop"); System.out.println("Set = " + set); List ...
