Create a grid of cards with Bootstrap 4, using the card-columns class.Set the grid inside the class − Include the card body inside the card container as in the following code snippet. I have added the card body under the card-class. The card-class is added inside the card-columns class − Accessories Let us see an example to create a grid of cards in Bootstrap −ExampleLive Demo Bootstrap Example Products Accessories Furnitures
Use align-top class to align an element with the top of the tallest element on the line.Align the element like this − Top Alignment Let us see an example to implement the align-top class in Bootstrap 4 −ExampleLive Demo Bootstrap Example Example This is demo text Demo Baseline Top Alignment Middle Alignment Bottom Alignment
The Arrays class of java package provides you a method named binarySearch() using this method you can perform a binary search on an array in Java.ExampleLive Demoimport java.util.Arrays; public class ArrayDemo { public static void main(String[] args) { int intArr[] = {30,20,5,12,55}; Arrays.sort(intArr); System.out.println("The sorted int array is:"); for (int number : intArr) { System.out.println("Number = " + number); } int searchVal = 12; int retVal = Arrays.binarySearch(intArr,searchVal); System.out.println("The index of element 12 is : " + retVal); } }OutputThe sorted int array is: Number = 5 Number = 12 Number = 20 Number = 30 Number = 55 The index of element 12 is: 1
You can convert an array list of strings to an array list of integers as:ExampleLive Demoimport java.util.ArrayList; import java.util.List; import java.util.stream.Collectors; public class LamdaExpressions { public static void main(String args[]) { ArrayList list = new ArrayList(); list.add("123"); list.add("223"); list.add("323"); list.add("334"); List listInteger = list.stream().map(s -> Integer.parseInt(s)).collect(Collectors.toList()); System.out.println(listInteger); } }Output[123, 223, 323, 334]
ExampleLive Demoimport java.util.Arrays; public class ArrayWithinAnArray{ public static void main(String args[]) { int[] myArray1 = {23, 56, 78, 91}; int[] myArray2 = {123, 156, 178, 191}; int[] myArray3 = {223, 256, 278, 291}; int[] myArray4 = {323, 356, 378, 391}; int [][] arrayOfArrays = {myArray1, myArray2, myArray3, myArray4}; System.out.println(Arrays.deepToString(arrayOfArrays)); } }Output[[23, 56, 78, 91], [123, 156, 178, 191], [223, 256, 278, 291], [323, 356, 378, 391]]
To process array elements, we often use either for loop or for each loop because all of the elements in an array are of the same type and the size of the array is known. Suppose we have an array of 5 elements we can print all the elements of this array as:ExampleLive Demopublic class ProcessingArrays { public static void main(String args[]) { int myArray[] = {22, 23, 25, 27, 30}; for(int i = 0; i
Yes, you can −int [] myArray1 = {23, 45, 78, 90, 10}; int [] myArray2 = {23, 45, myArray1[2], 90, 10};But, once you do so the second array stores the reference of the value, not the reference of the whole array. For this reason, any updating in the array will not affect the referred value −ExampleLive Demoimport java.util.Arrays; public class RefferencingAnotherArray { public static void main(String args[]) { int [] myArray1 = {23, 45, 78, 90, 10}; int [] myArray2 = {23, 45, myArray1[2], 90, 10}; System.out.println("Contents of the ...

Java provides a ByteBuffer class which allows you to wrap an array into a byte buffer using its wrap() method. Once you did that you can replace the contents of the buffer using the position(): To select the starting position and, put(): To replace the data methods:ExampleLive Demoimport java.nio.ByteBuffer; public class OverwriteChunkOfByteArray { public static void main(String args[]) { String str = "Hello how are you what are you doing"; byte[] byteArray = str.getBytes(); System.out.println("Contents of the byet array :: "); for(int i = 0; i
To find the intersection of two arrays in java use two loops. The outer loop is to iterate the elements of the first array whereas, the second loop is to iterate the elements of the second array. Within the second loop compare the elements of the two arrays:ExampleLive Demopublic class IntersectionOfTwoArrays { public static void main(String args[]) { int myArray1[] = {23, 36, 96, 78, 55}; int myArray2[] = {78, 45, 19, 73, 55}; System.out.println("Intersection of the two arrays ::"); for(int i = 0; i
A two-dimensional array in Java is represented as an array of one-dimensional arrays of the same type. Mostly, it is used to represent a table of values with rows and columns −Example Live Demopublic class Creating2DArray { public static void main(String args[]) { int[][] myArray = new int[3][3]; myArray[0][0] = 21; myArray[0][1] = 22; myArray[0][2] = 23; myArray[1][0] = 24; myArray[1][1] = 25; myArray[1][2] = 26; myArray[2][0] = 27; myArray[2][1] = 28; myArray[2][2] = 29; for(int i=0; i
