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
